| 摘 要： | 制备甲烷磺酸N-羟基琥珀酰亚胺酯,并将其应用于寡肽的液相合成.以N-羟基琥珀酰亚胺与甲烷磺酰氯反应制备甲烷磺酸N-羟基琥珀酰亚胺酯,并使其与Boc保护的酪氨酸、丙氨酸或Boc保护的酪氨酰脯氨酸发生SN2取代反应,生成相应的N-羟基琥珀酰亚胺活泼酯而活化羧基,并成功用于内吗啡肽-2和力肽的液相合成;N-羟基琥珀酰亚胺活泼酯的制备和应用反应条件温和、副产物少、收率较高.实验结果表明,甲烷磺酸N-羟基琥珀酰亚胺酯可用于寡肽的液相合成.

| Abstract: | The preparation of methanesulfonyl N-hydroxysuccinate and its use in the synthesis of oligopeptides in liquid phase has been studied.Methanesulfonyl N-hydroxysuccinate is synthesized from methanesulfonyl chloride and N-hydroxysuccimide,and used to prepare activated esters of N-Boc-Tyr-OH,N-Boc-Ala-OH,N-Boc-Tyr-Pro-OH by SN2 substituted reaction.In this study,methanesulfonyl N-hydroxysuccinate is successfully used in the synthesis of endomorphine-2(EM-2) and alanylglutamine.All the reactions can be operated under mild conditions with less side reaction and in high yield.The results show that methanesulfonyl N-hydroxysuccinate can perfectly meet the performance of oligopeptide synthesis in liquid phase. |
