Ketene bis(trimethylsilyl) acetals were reacted with α-halo acetals giving β-alkoxy-γ-halo acids which were converted to butenolides by reaction with two equivalents of base. This constitutes a novel and short butenolide synthesis.
使乙烯酮双(三甲基甲硅烷基)乙缩醛与α-卤代乙缩醛反应,得到β-烷氧基-γ-卤代酸,通过与两当量的碱反应将其转化为丁烯化物。这构成了新颖且短的丁烯内酯合成。
