These compounds compounds are also covered by the invention and can be used as such due to their biological activities or in negotia, suitable for individual components of finite mixtures of amide derivatives teicoplanin known (see European patent application N 218099 and International patent application N 88/06600).The amidation procedure described in these two publications, can also be used to produce compounds corresponding to this invention. These procedures include a condensation of the original carboxylic acids mentioned above, with an excess of the appropriate amine of formula II
where R1, Ala1, Ala2, Ala3X, T, p, q and W have the same meanings as above,
in an inert organic solvent in the presence of a condensing agent.Inert organic solvents used for the amidation reaction are aprotic organic solvents which do not adversely affect the course of the reaction and is capable of at least partially solubilisate source teicoplanin product.Examples of inert organic solvents are organic amides, complex alkalemia esters, ethers, glycols and polyhydric alcohols, phosphoramide imitacion, hexamethylphosphoramide, dimethylsulfoxide and mixtures thereof.The condensing agent used in this invention, suitable for the formation of amide bonds in organic compounds, in particular in the synthesis of the peptide.Typical examples of condensing agents are (C1-C4)alkyl, phenyl, or heterocyclic phosphorazidate, such as diphenylphosphonate, diethylphosphoramidite, di(4-nitrophenyl)phosphorazidate, dysmorphological and diphenylphosphinylchloride. The preferred condensing agent is diphenylphosphonate, i.e. azide complex of diphenyl ether phosphoric acid (DPPA). When carrying out the amidation process, as specified in this description, the amine reagent is generally used in molar excess amounts.Usually, when the amine reagent is inexpensive or quite easily obtained with a reagent used 2 6-fold molar excess, but preferred 3-4-fold molar excess.For amidation requires that Amin was capable of forming a salt with the carboxyl functional group teicoplanin the original product. When Amin is not subject to the second mixture to enter the salt-forming base is not less than ravnomyerno number of number of source teicoplanin.Use a small molar excess of amine reactant with the introduction of salt-forming base is quite suitable manner when the amine reactant is quite expensive and difficult to get a product.Examples of salt-forming bases are tertiary organic or heterocyclic amines, such as triethylamine, tromethamine, N-methyl pirrolidone or picoline, and others.The condensing agent is usually used in slight molar excess, amounting to, for example, 1.2 to 1.7-fold amount, preferably the 1.5-fold amount of teicoplanin source connection.In addition, amine reagent can be easily introduced into the reaction medium in the form of a suitable acid additive salts, such as hydrochloride. In this case, using a double molar ratio and preferably 2 to 4-fold molar excess of a strong base capable of free amine form of its salts. Along with this, in this case, the suitable base is a tertiary organic aliphatic or heterocyclic amine, such as described above. In fact, at least in some cases, the use of the amine salt, which is interesting, especially when this salt is more stable than the corresponding free amine.The reaction temperature usually varies within wide limits depending on the type of starting material and the reaction conditions. Usually it is desirable to carry out the reaction at temperatures in the range 0-20oC.In addition, the reaction time also varies widely depending on other parameters of the reaction. Usually the condensation reaction is completed within about 24 to 48 hoursIn any case, the course of the reaction is controlled by thin-layer (TLC) chromatography or liquid chromatography high resolution (HPLC) according to existing methods.Based on the results of these analyses specialist in this area to assess the progress of the reaction and to decide when to stop the reaction and when to begin treatment of the reaction mass according to known techniques, which include, for example, extraction with solvents, precipitation by entering nerastvorimaya, etc. in combination with other well-known operations of separation and purification, for example by using columnar chromatography.If the amine reactant contains other functional groups, which is imayutsya through already known protective groups.According to the following preferred aspect of the invention: compounds of formula I in which Y represents the above group can be obtained by reaction of the "activated complex ether carboxylic acids of the same formula I in which Y is OH, and N15-amine functional group is preferably protected with an appropriate amine of formula II.N15-amine functional group may be protected by known methods (see, for example, kN. T. W. Greene. "Protective groups in organic synthesis". John Wiley and Sons. New York. 1981; M. Mc. Omie. "Protective groups in organic chemistry". Plenum Press. New York. 1973).The protective group must be stable in the reaction should not have an adverse impact on the amidation reaction and should be easily cleaved and removed from the reaction medium after the reaction without changing the newly formed amide bond and the General structure of the compounds, such as components of sugar.Typical examples of the N-protective groups which can be successfully used in the method of the present invention to protect the N15-primary amine functional group source teicoplanin, and when it is needed, and who embody the following oxycarbonyl groups: I, I dimethylphenylcarbinol, tert-butyloxycarbonyl, vinyloxycarbonyl, cinnamoylcocaine, benzyloxycarbonyl, para-nitrobenzenesulfonyl, 3,4-dimethoxy-6-nitrobenzisoxazole, 2,4-dichlorobenzenesulfonyl, 5-benzyloxycarbonyl, 9-internalservererror, diphenylmethylsilane, isonicotinamide, diphenylmethylsilane, isonicotinamide, S-benzyloxycarbonyl and others. Other suitable N-zameshayushei agents are aldehydes or ketones or their derivatives, which are capable of forming Schiff bases with amine group that must be protected.Preferred examples of such agents, forming a Schiff base, are benzaldehyde and particularly preferred is 2-oxybenzaldehyde (salicylic aldehyde).A simple method of protection in some cases is the formation of benzylidene derived, which can be obtained by reaction of the amine with benzaldehyde in a lower alcohol, such as ethanol, preferably at room temperature. After stopping the reaction with the selected teicoplanin source material benzylidene protective group can be removed already known the th media as a catalyst.However, in this case, you should pay attention to the presence of groups that can be modified by catalytic hydrogenation. A typical consequence of the catalytic hydrogenation of an amino-protected derivative of the formula I, in which And represent the above group, in which the acyl is (Z)-4-decenal(or its containing mixture), is the fact that at least partially decanoate connection turns into a corresponding Technologie connection.As should be clear to experts in this field, the selection of specific protective group depends on the characteristics of a specific amide derivative, which is desirable. In fact, this amide functional group end of the connection must be stable under the conditions of removal of the protective group (or groups).As the conditions for the removal of various functional groups known to the person skilled in the art can choose a suitable protective group.Getting "activated esters" is known (see Fieser and Fieser. Reagents for organic synthesis. John Wiley and Sons Inc. S. 129 130, 1967).Examples of reagents that form these activated complex EF is Schwyzer and other Helv. Chim. Acta 1955 , 69-70, and include the following compounds: ClCH2CN, BrCH2COOC2H5, BrCH(COOC2H5)2, CICH2COCH3, , ClCH2CH2N(C2H5)2.The preferred reagent of this type is chloroacetonitrile. In this case, itself chloroacetonitrile or dimethylformamide (DMF) can be used as a preferred solvent.Usually inert organic solvents used to get "activated esters" are aprotic organic solvents which do not adversely affect the course of the reaction and is capable of at least partially to solubilisate original carboxylate.Examples of these inert organic solvents are organic amides, alkalemia ethers, ethers of glycols and polyols, phosphoramide, sulfoxidov and aromatic compounds. Preferred examples of inert organic solvents are dimethylformamide, dimethoxyethane, hexamethylphosphoramide, dimethyl sulfoxide, benzene, toluene, and mixtures thereof.More preferably, the solvent is selected from among the following: acetatee Foundation, which does not affect the course of the reaction, such as trialkylamine, such as triethylamine, sodium carbonate or sodium bicarbonate or potassium. Typically, the base used in the 2-6-molar proportions to the original carboxylic acid teicoplanin, preferably it is approximately 3-fold molar excess. The preferred base is triethylamine.The reagent, forming an "activated ester" is used in large excess relative to the carboxylic acid source teicoplanin. It is typically used in 5-35-molar ratio, preferably about 20-30-fold molar excess. The reaction temperature is 10 to 60oC, preferably 15 to 30oC. Typically, the duration of the reaction depends on other specific parameters of the reaction and is usually 3: 48 PMIn this case, the course of the reaction can be traced by thin layer (TLC) chromatography and liquid chromatography high resolution (HPLC) to determine when the reaction can be considered as completed and when may be the procedure of retrieving the desired intermediate product. Intermediate product "activated ester" can use is Sardinia nerastvorim or by solvent extraction and is used as such without further purification in the next reaction step. However, if desirable, it can be purified by columnar chromatography, such as chromatography with evaporative column or a chromatography column with a reversible phase.The obtained intermediate product "activated ester" then reacted with a molar excess of amine derivative of the formula II
in the presence of an organic polar solvent at a temperature 5 - 60oC, preferably 10 to 30oC.Organic polar solvent in this case can be proton polar solvent or aprotic solvent.Preferred examples of the organic proton polar solvents are low (C2-C4)alkanols, such as ethanol, n-propanol, ISO-propanol, I-butanol, etc. or mixtures thereof, preferably used in the dry form.Preferred examples of the organic polar aprotic solvent is N,N-dimethylformamide (DMF), hexamethylphosphoramide (HMPA), or mixtures thereof, 1,3-dimethyl-3,4,5,6-tetrahydro-2(IH)-pyrimidone (DMPU), dimethylsulfoxide (DMSO) or dimethoxyethane (DME).The reaction of the "activated complex ester" SEL which is temperature 10 30oC, most preferably 20 to 25oC, while the preferred molar ratio between the intermediate activated complex ester and amine II, as defined above, is (1 5) (1 to 30), more preferably (1 10) (1 20). The course of the reaction can be adjusted as accepted by TLC or HPLC.Amide derivative obtained by the amidation reaction, is removed from the reaction solution according to the conventional procedures, for example by evaporation of the solvent or by entering herstories. The removal of the amine protecting group is usually carried out on the crude product isolated from the reaction medium amidation.Examples of processes for the removal of these protective groups from teicoplanin derivatives are known (see, for example, International patent application N WO 88/06600).If the procedures of the catalytic hydrogenation reaction is usually carried out in the presence of a diluted aqueous solution of a strong acid, preferably an inorganic acid, an organic solvent, is mixed with a dilute aqueous solution of a strong acid. The filtrate from the reaction medium is then processed to extract either additive or toxic treatments are carried out in the case, when the amine protecting group is one which can be removed by treatment with diluted inorganic acid, such as Schiff base or a carbonyl group C-C alkoxy, in conditions which do not cause cleavage of the sugar units, such as low temperature, short reaction time.The following procedure for obtaining compounds of formula I according to the invention consists in the reaction of N15-protected derivative of N63amide of the formula I in which Y represents-NR1Ala, XH or NR1-Ala1-[X-Ala2]p-TH reagent of the formula r-[ALK]p-[T-Ala3]q-W or r-[Ala3]qW, respectively, where R1, Ala1, Ala2, Ala3, X and T have the same values as above, r represents halogeno, methanesulfonyl or tosyl, in the presence of an acid acceptor in an inert solvent. In these cases, p is preferably 1 or 2, q has a value other than zero, is preferably 1 or 2, X and T are preferably NH or oxygen, most preferably oxygen. N15-protected derivative of N63amide above, obtained according to the General description of the JV the uly I, in which W represents-NR8R9-, where R8defined above, R9is a group COOR10and R10(C1-C6) acyloxy-(C1-C4) alkyl, you need to N15-protected derivative of N63amide, in which W represents-other8-, where R8defined above, interacted with alpha-acyloxy-alkyl-para-nitrophenylarsonic in the presence of anhydrous carbonate of an alkali metal such as sodium carbonate.Alpha-acyloxy-alkyl-para-nitrophenylarsonic can be obtained in a known manner (see J. Med. Chem. 31, S. 318 322. 1988). Some amides, corresponding to the invention, such as amides complex teicoplanin A2that is a separate component, or any mixture of two or more of its components, can be used as a starting material to obtain unitary antibiotic products by selective hydrolysis of one or two sugar molecules with the existence of procedures thus, as already described in the European patent N 119575 and N 119574.
