摘要
从2-羟基-4-甲氧甲氧基苯乙酮和3，5-二甲氧基苯甲醛出发，通过醛酮缩合、环化、Algar-Flynn-Oyamada反应、脱保护基、异戊烯基化反应等步骤，合成了5个未见文献报道的7-羟基黄酮醇和7-羟基黄烷酮及其衍生物，总收率22％～36％。其结构经^1H NMR，^13C NMR，IR和MS确证。
Five novel 7-hydroxyflavonols, 7-hydroxyflavanones and their derivatives were synthesized by aldol condensation, eyelization, Algar-Flynn-Oyamadg reaction, deproteetion and O-prenylation. The overall yields were 22%～36%. Their structures were confirmed by ^1H NMR, ^13C NMR, IR and MS.
