ABSTRACT:
Disclosed is a process for the manufacture of pseudo proline dipeptides of the formulawherein R1is a side chain of an alpha amino acid, R2is an amino protecting group and R3and R4are independently either hydrogen or C1-4-alkyl, and R5is hydrogen or methyl starting from an amino acid derivative of the formulawherein R1and R2are as defined above. Pseudo proline dipeptides can be used as reversible protecting groups for Ser, Thr and Cys and thus are versatile tools in peptide chemistry.
