摘要
本文采用相转移法,使乙酰基-α-D-溴代糖1(A-C)与6-(4-甲氧基)苯基-3(2H)-哒嗪酮2以及6-(4-羟基苯基)-4,5-二氢-3(2H)-哒嗪酮5反应合成了3(A,C)及6(A,B)四个乙酰基糖苷化合物.其中3A经氨解脱去保护基又得到一个化合物4A′.其结构被IR、1HNMR和元素分析所证实.
Two N-glycosides 3 ( A, C ) of 6- (4-methoxyphenyl) -3 (2H) -pyridazinone 2 and two O-glycosides 6 ( A, B ) of 6-(4-hydroxyphenyl) -4,5-dihydro-3 (2H) -pyridazinone 5 were synthesized under phase transfer catalysis. Compound 3A was treated by ammonia to give compound 4A′. Their structures were confirmed by elementary analysis, IR, and ^1HNMR.
