摘要
在相转移催化条件下,使2 ,3 ,4三O乙酰基1溴1脱氧αD木吡喃糖(1) 同2烷氧基(2苯硫基)5氟3 H4嘧啶酮(2a～2e) 反应,合成了2烷氧基(2苯硫基)3N(2 ,3 ,4三O乙酰基βD木吡喃糖1基)5氟4嘧啶酮(3a～3e) .(1) 与(2a～2e) 的银盐(4a ～4e) 在二甲苯中发生KoenigsKnorr 反应,合成了2烷氧基(2苯硫基)4O(2 ,3 ,4三O乙酰基βD木吡喃糖1基)5氟嘧啶(5a～5e) .化合物(3) 和(5) 的结构经红外光谱、核磁共振氢谱、质谱或元素分析所证实.初步的体外杀伤癌细胞试验表明。
Alkoxy(2 phenylthio) 3 N (2,3,4 tri O acetyl β D xylopyranos 1 yl) 5 fluoro 4 pyrimidone(3a～3e)were synthesized by the condensation of 2,3,4 tri O acetyl 1 bromo 1 deoxy α D xylopyranose(1)with 2 alkoxy(2 phenylthio) 5 fluoro 3 H 4 pyrimidone(2a～2e)under phase transfer catalysis.2 Alkoxy(2 phenylthio) 4 O (2,3,4 tri O acetyl β D xylopyranos 1 yl) 5 fluoro pyrimidine(5a～5e)were obtained by the Koenigs Knorr reaction of (1) with the silver salts(4a～4e) of (2a～2e)in xylene.Ten new compounds with structure (3) and (5) were synthesized and their structures were confirmed by IR, 1H NMR,MS or elementary analysis.Preliminary results of the in vitro tests on KB,HCT 8 tumor cells showed that some of them were of certain antitumor activities.
