新的5,3',5'-三羟基7-甲氧基黄酮及其一,二和三苄氧基衍生物的合成
Synthesis of a Novel 5,3’,5’-Trihydroxy-7-methoxyflavoneand Its Mono-,Dibenzyloxy-derivatives via Selective Deben- zylation of 5,3’,5’-Tribenzyloxy-7-methoxvflavone
【摘要】 通过3.5-二苄氧苯甲酸-2,6-二羟基-4-甲氧基苯丙酮酯进行Baker-Venkatara-man重排,环化合成了5,3',,5,三苄氧基7-甲氧基黄酮,然后选择性地和全部地脱节基得到5,3',5'-三羟基-7-甲氧基黄酮及其一和二苄基衍生物.
【Abstract】 The novel compound 5,3’,5’-trihydroxy-7-methOxyflavone was synthe sized twi complete debenzylation of 5,3’,5’-tribenzyloxy-7-methoxyflavone,The latter was also selectively debenzylated to give the mono-and di-benzyloxyflavone.
