摘要

Abstract Coupling an unprotected amino acid or dipeptide in partially aqueous solution with a readily available N-(Z-α-aminoacyl) benzotriazole or N-(Z-α-aminopetidoyl) benzotriazole affords N-terminal-protected di-, tri-, and tetrapeptides in yields of 85-98%(average 95% for 2a-i, 93% for 4a-f and 4a′, 86% for 5a-b) with minimal epimerization.
