Base-induced intramolecular cyclization of novel (4-aryl-2,4-dioxobutyl)methylphenylsulfonium salts prepared from the commercially available 1-arylethanone by a cost-effective process is described in this paper. The reaction was completed within 10 min to produce a family of 2-unsubstituted 5-aryl-3(2H)-furanones in excellent yield. This procedure is simple, and can be carried out under mild conditions
本文描述了一种由碱诱导的新型(4-芳基-2,4-二氧丁基)甲基苯基s盐的分子内环化反应,该盐是通过经济有效的方法从市售的1-蒽酮制备的。反应在10分钟内完成,从而以优异的收率生产出一系列2-未取代的5-芳基-3(2 H)-呋喃酮。该过程很简单,并且可以在温和的条件和环境气氛下进行。
