摘要

Abstract

It is reported that alkali-metal borohydrides (MBH

M = Li

Na and K) are efficient catalysts for ring opening polymerization (ROP) of

-amino acid

-carboxyanhydrides (NCAs). Polypeptides are prepared in quantitative yields with relatively narrow molecular weight distributions (MWDs = 1.1~1.5) which depend on the reaction temperature. End groups of the produced polypeptide are studied in detail by MALDI-ToF MS

H-NMR

C-NMR

H-

H COSY and

H-

C HMQC analyses. The results indicate that

-hydroxy-

-aminotelechelic polypeptides are formed which are suitable for post-polymerization functionalization.
