中文摘要：

以L-脯氨酸和L-丝氨酸为原料,1-（3-二甲氨基丙基）-3-乙基碳二亚胺盐酸盐（EDC.HCl）为缩合剂,将C端和N端分别通过烯丙基和Fmoc保护的L-丝氨酸与乙酰基保护的L-脯氨酸缩合得到N-乙酰基-L-脯氨酸-Fmoc-L-丝氨酸烯丙酯二肽酯。脱去Fmoc保护后,再与2,3,4-O-三乙酰基-6-O-三氟甲磺酰基-α-D-甲基吡喃葡萄糖苷作用,得到N-乙酰基-L-脯氨酸-N-6-（2,3,4-O-三乙酰基-α-D-甲基吡喃葡萄糖苷）-L-丝氨酸烯丙酯二肽酯,通过核磁共振氢谱、高分辨质谱对其结构进行了表征。

英文摘要：

Using L-proline and L-serine as raw materials,EDC·HCl as coupling reagents,L-N-acetyl-pro-N-Fmoc-L-ser-（O-allyl） dipeptide ester were obtained by coupling reaction of L-N-acetyl-proline and N-Fmoc-L-serine allyl ester.After deprotecting Fmoc,the substitution reaction of obtained compound and 2,3,4-tri-O-acetyl-6-O-triflyl-α-D-glucopyranoside occurred,giving N-Acetyl-L-pro-N-glucopyranoside-L-ser dipeptide ester.The structures of the final product and intermediates were characteried by 1H NMR,HR-MS.
