Disclosed is a process for the manufacture of pseudo proline dipeptides of the formula
wherein R
1
is a side chain of an alpha amino acid, R
2
is an amino protecting group and R
3
and R
4
are independently selected from hydrogen or C
1-4
-alkyl, R
5
is hydrogen or methyl starting from an amino acid derivative of the formula
wherein R
1
and R
2
are as above.
Pseudo proline dipeptides can be used as reversible protecting groups for Ser, Thr and Cys and thus are versatile tools in peptide chemistry.
本发明揭示了一种制备伪脯氨二肽的方法,其化学式为其中R1是α-氨基酸的侧链,R2是氨基保护基团,R3和R4分别独立选自氢或C1-4-烷基,R5是氢或甲基,起始于化学式的氨基酸衍生物其中R1和R2如上所述。伪脯氨二肽可用作Ser、Thr和Cys的可逆保护基,因此是肽化学中多用途的工具。
