摘要/Abstract

首先通过九步反应合成了一系列L-苏糖嘧啶核苷膦酸酯. 用二乙胺基三氟化硫(DAST)处理L-苏糖嘧啶核苷膦酸酯, 分别以中高收率得到相应的2,2'-缩水-1-(L-苏糖)尿嘧啶核苷膦酸酯类似物. 对所得到的L-苏糖嘧啶核苷膦酸酯和2,2'-缩水-L-苏糖嘧啶膦酸核苷进行了初步的生物学评价, 未发现任何活性.

关键词: 2,2'-缩水核苷, 二乙胺基三氟化硫(DAST), L-苏糖嘧啶膦酸酯

A series of L-threoylnucleoside phosphonates were synthesized via a nine-step procedure firstly. When the L-threoylpyrimidine nucleoside phosphonate was treated by diethylaminosulphur trifluoride (DAST), all the tried pyrimidine L-threosylnucleoside phosphonate analogues produced corresponding 2,2'-anhydro-1-(L-threoyl)pyrimidine phosphonates in medium-high yields. The obtained L-threoylpyrimidine nucleoside phosphonates and 2,2'-anhydro-L-threosylpyrimidine phosphonic acids have not shown any activity by primary biological evaluations.

Key words: 2,2'-anhydronucleoside, diethylaminosulphur trifluoride (DAST), L-threosylpyrimidine phosphonate
