    Abstract: The invention relates to a method for producing compounds of the general formula (I) in which R is hydrogen, C1-C6-alkoxy, -NHC1-C6-alkyl, -N(C1-C6- alkyl)2, OH, NH2; R1 is hydrogen, C1-C6-alkyl, Me3Si, C1-C6-alkyl-S; R2 is Boc, C1-C6-acyl, mesyl, benzolsulfonyl, tosyl, trifluoroacetyl, A1-A3-peptid e; n is 1, 2; and R4 is H, C1-C6-alkyl rest. According to said method a pyrroli ne or dehydropiperidine derivative of the general formula (II) is reacted with a strong base and a compound of the general formula (III), in which Y is Cl, C 1- C6-alkoxy, -NHC1-C6-alkyl, -N(C1-C6-alkyl)2, N(C1-C6-alkyl) OC1-C6, where R is not equal OH, or with carbon dioxide when R = OH. The reaction product of (I I) and (III) is possibly hydrolyzed or reacted with a compound of the general formula (IV) R1~X, in which X is Cl, Br, I, MesO, TosO, triflate, R1 is hydrogen, C1-C6-alkyl, Me3Si, C1-C6-alkyl-S or NH4, or R1~X is (C1-C6-alkyl- 'S)2.
