Abstract

Aroyl-S,N-ketene acetals are obtained by condensation of aroyl chlorides and 2-methyl-N-benzylbenzothiazolium salts in 1,4-dioxane at room temperature in short reaction time in 20-99% yield. This protocol represents a considerable improvement over the standard synthesis in 1,4-dioxane/ethanol mixtures at elevated temperatures.

省略醇共溶剂,优化了芳烃- s, n -烯酮缩醛的合成。
在室温下,芳烃氯与2-甲基- n -苄基苯并噻唑盐在1,4-二恶烷中缩合,反应时间短,产率为20-99%,得到了芳烃- s, n -烯酮缩醛。该方案代表了在1,4-二恶烷/乙醇混合物中在高温下的标准合成的相当大的改进。
