Activation of N,N-bis-Boc or N-Boc N-Z amino acids with SOCl2–DMF leads to N-protected N-carboxy amino acid anhydrides, whereas treatment with cyanuric fluoride at low temperature gives mainly N,N-bis-protected amino acid fluorides, which are efficient acylating agents.
用 SOCl2-DMF 活化 N,N-二叔丁氧羰基或 N-叔丁氧羰基 N-Z 氨基酸会产生受 N 保护的 N-羧基氨基酸酐,而在低温下用三聚氰酸氟化物处理则主要产生 N,N-二保护氨基酸氟化物,它们是高效的酰化剂。
