PSEUDO PROLINE DIPEPTIDES
Disclosed is a process for the manufacture of pseudo proline dipeptides of the formula wherein R1 is a side chain of an alpha amino acid, R2 is an amino protecting group and R3 and R4 are independently either hydrogen or C1-4-alkyl, and R5 is hydrogen or methyl starting from an amino acid derivative...

Summary: | Disclosed is a process for the manufacture of pseudo proline dipeptides of the formula wherein R1 is a side chain of an alpha amino acid, R2 is an amino protecting group and R3 and R4 are independently either hydrogen or C1-4-alkyl, and R5 is hydrogen or methyl starting from an amino acid derivative of the formula wherein R1 and R2 are 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. |
