Abstract

A procedure for the preparation of new amino acid derivatives of the general formula (I) **(See formula)** where R means a hydrogen atom or an alcohol group with 1 to 4 carbon atoms, n means an integer from 1 to 3, and m means 2 or 3, as well as the optically active salts and isomers of these positions, characterized in that compounds of the general formula (II) are reacted **(See formula)** wherein R7 signifies an aralkoxy, formyl, trifluoroacetyl or p-toluenesulfonyl group, a benzyloxycarbonyl group, a -CO- group or a group of the formula (see formula) (in which R15 means an alcohol group with 1 to 4 carbon atoms, a cycloalcohyl group, an optionally substituted aralcohyl group or an optionally substituted aryl group), R8 means a hydrogen atom or a -CO- group, with the proviso that in case R7 = R8 = -CO- group, R7 and R8 are closed on an orthophenylene group to form **(See formula)** the compounds obtained from the general formula (IV) are oxidized **(See formula)** and they are cleaved from the compounds obtained from the general formula (V) **(See formula)** the protecting groups of the alpha-amine group and the compounds obtained from the general formula (VI) are subjected **(See formula)** to an enzymatic acidolysis, hydrogenolysis or hydrolysis and the compounds obtained are converted into their salts or liberated from their salts and/or the compounds are prepared in the form of their optically active isomers using for this purpose optically active reagents in any reaction step or by subjecting the compounds to a racemate separation.
