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,部分化合物具有一定抗肿瘤活性
In the phase transfer catalytic conditions, so that 2, 3, 4 3 O acetyl 1 bromine 1 deoxy α D pyranose sugar (1) with 2 alkoxy (2 benzene Thio) 5 fluorine 3 H 4 pyrimidinone (2a ~ 2e) reaction, the synthesis of 2 alkoxy (2-phenylthio) 3 N (2,3,4 three O acetyl β D wood pyranose sugar 1 base 5 fluorine 4 pyrimidone (3a ~ 3e). (1) and (2a ~ 2e) of the silver salt (4a ~ 4e) Koenigs Knorr reaction occurred in xylene, the synthesis of 2 alkoxy (2-phenylthio) 4 O (2, 3, 4 O O acetyl β D wooden pyran Sugar 1 base 5 fluoropyrimidine (5a ~ 5e) .The structures of compounds (3) and (5) were confirmed by IR, 1H NMR, MS or elemental analysis.Preliminary in vitro killing of cancer cells Show that some compounds have some anti-tumor activity
