An efficient and general synthesis of benzopyrans is achieved by ethylenediamine diacetate-catalyzed reactions of resorcinols with α,β-unsaturated aldehydes in moderated yields. As an application of this methodology, biologically interesting confluentin, which was known to have an inhibitory effect on histamine release is synthesized in one step. Also, natural daurichromenic acid, which has highly
通过乙二胺二乙酸酯催化间苯二酚与α,β-不饱和醛的适度收率,可实现苯并吡喃的有效和一般合成。作为该方法的一种应用,一步合成了生物学上有意义的融合蛋白,已知该蛋白对组胺的释放具有抑制作用。此外,一步法成功地合成了具有强大的抗HIV活性的天然金鸡铬酸。
