You can use variations, known by themselves.

The initial substance can be formed at will, they are not isolated from the reaction mixture, and immediately used for further compounds of formula I.

The compounds of formula I can be obtained from their functional derivatives by solvolysis, in particular hydrolysis, or by hydrogenolysis.

The preferred initial agents for the process of the solvolysis or hydrogenolysis are those which correspond to the formula I, but instead of one or more free amino and/or hydroxyl groups contain appropriate protective amine and/or gidrookisyei group, preferably such that instead of H-atom with a N-atom, contain aminosidine group, in particular, the e, which, instead of the H-atom of actigraphy contain a hydroxy protective group, for example those which correspond to formula I, but instead of the group-COOH contain a group-COOR", where R" means oxidising group.

In the original substance may contain several identical or different protective amine and/or exigrep. If the existing protective groups differ from each other, they can be selectively separated.

The expression "aminosidine group" is well known and refers to groups who are able to defend /block/ amino group from chemical reactions of metabolism, which, however, can easily be removed after carrying out the desired chemical reactions in the presence of the molecule in different location. Such typical groups are, in particular, unsubstituted or substituted acyl, aryl - /for example, 2,4-dinitrophenyl (DNP)/, Alcoceber- /for example, benzoyloxymethyl (BOM) and/ or Uralkaliy /for example, benzyl, 4-nitrobenzyl, triphenylmethyl/. As aminosidine group in the reaction are removed, their type and size in General are not critical; will be preferred, however, are those which have 1 to 20, especially 1 to 8 C-atoms. The expression "acyl group" in connection with the proposed method it is necessary to understand in Shiro or heterocyclic carboxylic acids or sulphonic acids, and, in particular, alkoxycarbonyl, aryloxyalkyl - and, above all, alcoxycarbenium. Examples of such acyl groups is alkanoyl as acetyl, propionyl, butyryl; arcanol as phenylacetyl; aroyl as benzoyl or toluyl; aryloxyalkanoic as phenoxyacetyl; alkoxycarbonyl as methoxycarbonyl, etoxycarbonyl, 2,2,2-trichlorocyanuric, isopropoxycarbonyl, tertiary butoxycarbonyl /BOC/ 2-iodoxybenzoic; Uralelectromed as benzyloxycarbonyl /CBZ/, 4-methoxybenzenesulfonyl, 9-fluorenylmethoxycarbonyl /FMOC/. Preferred aminosidine groups are BOC, DNP and BOM, in addition CBZ, benzyl and acetyl.

The expression "oxycodine group" is also generally known and relates to groups able to protect oxygraph from chemical reactions of metabolism, which, however, can be easily removed after carrying out the desired chemical reactions in the presence of the molecule in different location. Typical groups are the abovementioned unsubstituted and substituted aryl, aralkyl or accelgroup, in addition also altergroup. The nature and dimensions oxidising groups are not critical, since they are removed again after the desired chemical reaction; preferred ablauts is benzyl, p-nitrobenzoyl, p-toluensulfonyl and acetyl, and especially preferred are benzyl and acetyl.

Used as source materials for the functional derivatives of compounds of formula I can be obtained by conventional methods described in these sources and patent applications, for example using the exchange reaction of decomposition of the compounds, and, however, at least one of these compounds contains a protective group instead of the H atom.

The release of the compounds of the formula I from their functional derivatives is in accordance with the used protective group, for example using strong acids, expediently triperoxonane acid or perchloric acid and other strong inorganic acids, such as hydrochloric or sulfuric acid, strong organic carboxylic acids, such as trichloroacetic acid, or sulfonic acids, such as benzene - or p-toluensulfonate. The presence of an additional inert solvent may, but is not always necessary.

As inert solvents are suitable mainly organic solvents, for example carboxylic acids, as acetic acid, ethers, nab, which measures dichloromethane, solitarii, such as dimethylsulphoxide /DMSO/, in addition, also alcohols, such as methyl, ethyl, isopropyl, and water. In addition, it is worth mentioning mixtures of the aforementioned solvents. Triperoxonane acid is preferably used in excess without the addition of another solvent, perchloric acid in the form of a mixture of acetic acid and 70% perchloric acid in the ratio 9:1. Reaction temperatures for the cleavage are expediently between 0 and 50oC, preferably the reaction is carried out at room temperature /15 - 30o/.

Reaction occurs when adding a base, such as triethylamine or ethyldiethanolamine in an inert solvent or combination of solvents, for example water/dioxane at temperatures of 0 - 120o, preferably 60 to 120o. Then you can transform the compound of formula I, one or both of the residues R1and/or Y in other /no residue/Ki R1and/or y

In particular, it is possible to restore a cyano group aminomethyl or turn into a group of amidine or hydroquinidine, group carboxyla to atrificial, ether group split, the benzyl group to remove the Hydra is gruppe group aminomethyl possible using catalytic hydrogenation, for example, Raney Nickel, at a temperature of 0 - 100opreferably 10oand 30oand a pressure of 1 to 200 bar, preferably at normal pressure, in an inert solvent, for example in a lower alcohol as methyl or ethyl, expediently in the presence of ammonia. If the temperature of, for example, 20oand a pressure of 1 bar, the original material is retained existing group of benzylamine or N-benzyl. They are necessary and can split the hydrogenolysis using a catalyst of a noble metal, preferably Pd-coal, which can be added to a solution of the acid, for example acetic acid, and water.

To obtain amidine formula I /R1= lidinopril/ can to the nitrile of formula (I /R1= tianfei/ attach ammonia. The joining is preferably in several stages,

and/ nitrile with H2's turn in thioamide, who with the help of alkylating substances, such as CH3I transferred to the corresponding S-alkalinization, which, on its part reacts with NH3to obtain amidine,
