ABSTRACT:
Compounds having the general formula: ##STR1## in which R3 represents an aryl group which is unsubstituted or substituted by one or more alkyl groups containing 1 to 4 carbon atoms; R4 represents a hydrogen atom, a group for protecting the amino functional group, an amino acid or a peptide some of whose functional groups are optionally substituted by a protecting group or by an activating group; R5 represents a hydroxy group, a halogen atom, a group for protecting the carboxyl functional group, an activating group, an amino group, an amino acid or a peptide some of whose functional groups are optionally substituted by a protecting group or by an activating group; and n is an integer from 1 to 10.
