Abstract

Dipeptides contg. N-terminal-carboxy-alkyl gps. of gluerol formula (1), as N-(1(S)-carboxy 3-phenyl-propyl)-S-alanyl (S)proline-derivs., where R = a hydrogen atom or a known peptide chemistry protective gp.; R1 = 1-4C alkyl gp. or such an alkyl-amino gp. which is protected as in this case - are prepd. from a di:peptide of formula (111) where R and R1 are as before and from 4-phenyl-4-oxo-butenoic acid-benzyl ester. Cpds. (11) is separated from its soln. in the reaction mix, as an acid adduct salt. (R and R1 unchanged). The acid adduct, in this case, is formed with a strong acid. - The product may be liberated from the adduct or used as an acid adduct or as a basic salt.
