prepared. Judging from the result of model dipeptide (Z-Ala-Phe-OMe) formation, these compounds are found to be new effective additives for peptide synthesis by the dicyclohexylcarbodiimide (DCC) method at the points of high yield and no detectable racemization.
制备含 N-羟基酰胺的杂环、1-羟基-4,6-二甲基-2(1H)-
嘧啶酮和-5,6-二甲基-2(1H)-
吡嗪酮。从模型二肽(Z-Ala-Phe-OMe)形成的结果来看,这些化合物被认为是二环己基碳二
亚胺(
DCC)法合成肽的新型有效添加剂,具有高产率和无外消旋化的特点。
