  摘要：

  羧酰胺官能团可以通过在冰醋酸中与三苯甲醇和乙酸酐进行酸催化反应来三苯甲基化。天冬酰胺和谷氨酰胺的ω-三苯甲基可被TFA裂解，但对水溶液中的强无机酸以及亲核试剂和碱稳定。在肽合成中，它非常适合与叔丁基类型的侧链保护结合使用。

Application of α- and β-Nsmoc amino acids to the solid-phase synthesis of two model peptides was examined. An advantage of the α-Nsmoc system over the long-known Bsmoc system proved to be the milder conditions needed for
