一种合成环丁烯酮衍生物的新方法

摘要

介绍了一种在碱性条件下以α-丙酰基二硫缩烯酮与胺类化合物为反应原料,DMSO 为反应溶剂,发生分子内环化反应合成环丁烯酮衍生物的新方法。其中合成了3个新化合物,产物结构经1 H NMR 确证。%A novel and efficient route was introduced to synthesize cyclobutenones developed via an intramolecu-lar annulation reaction of α - propionyl ketene - S,S - acetals under base conditions, DMSO as reaction solvent. 3 new compounds were synthesized and confirmed by 1 HNMR.
