摘要
报道了一种简便高效地构建黄酮及喹啉酮衍生物的方法.实验发现,以廉价易得的四水合硫酸化铈[Ce(SO_4)_2·4H_2O]作为氧化剂,2'-羟基査尔酮或2'-氨基查尔酮为原料,在二甲基亚砜(DMSO)中,110℃下,环合生成相应的黄酮和喹啉酮衍生物.其特点是原料易得、价格低廉、反应条件温和及收率高.
A simple and powerful procedure for the synthesis of flavones and quinolones was developed by using Ce(SO4)2·4H2O as oxidant, readily available 2'-hydroxychalcones and 2'-aminochalcones as raw materials, and dimethyl sulfoxide (DMSO) as solvent at 110℃. The new procedure is characterized with raw material easy to get, low manufacturing cost, mild reaction condi-tions and high yields.
