    摘要: In the synthesis of a polypeptide chain wherein an N.sup..alpha. -urethane-protected amino acid mixed anhydride is coupled with an amino-unprotected second amino acid, the improvement comprising conducting said coupling at room temperature or above. This method provides rapid, essentially quantitative reactions without the necessity for reduced temperatures. The method is particularly useful in the solid-phase synthesis of peptides where shortened coupling cycles and improved yields of substantially pure products are obtained.
