7,7″-Dimethoxy cupressuflavone, 7,7″-dimethoxy 5,5″,4′,4‴-tetraacetoxy cupressuflavone, cupressuflavone hexamethylether and 7,7″,4′,4‴-tetramethoxy cupressuflavone have been synthesized by a new route via the corresponding bichalcones. It has the advantage over the synthesis via 8-iodo-apigenin trimethylether,2 that in the last step of demethylation of cupressuflavone hexamethylether, the possibility
通过一种新的方法合成了7,7″-二甲氧基铜黄酮,7,7″-二甲氧基5,5″,4′,4′-四乙酰氧基铜黄酮,cupressuflavone六甲基醚和7,7″,4′,4′-四甲氧基铜黄酮。路线通过相应的bichalcones。它具有以下优点:在经由-8-碘芹菜素trimethylether,合成2在cupressuflavone hexamethylether的去甲基化的最后一个步骤,可避免Wessley-Moser的重排的可能性。3
