The new efficient synthesis of biologically important 3-hydroxy-4-arylquinolin-2-ones through the Darzens condensation (epoxidation) of dichloroacetanilides with aromatic aldehydes followed by one-pot dechlorative epoxide-arene cyclization is described. This methodology has been utilized for the synthesis of naturally occurring viridicatol, a fungal metabolite isolated from the penicillium species
描述了一种新的有效的生物重要的3-羟基-4-芳基喹啉-2-酮的有效合成方法,该方法是通过二氯乙苯胺与芳族醛的Darzens缩合(环氧化),然后进行一锅式脱氯环氧-芳烃环化。该方法已用于合成天然存在的维地卡多,这是一种从青霉菌属中分离出来的真菌代谢产物。
