ABSTRACT An efficient copper-catalysed tandem reaction to synthesize thiazol-2(3H)-one structures from readily available raw materials is described. The protocol provides a cost-effective approach to a decent range of nitrogen and sulfur bearing heterocycles in acceptable yields. The transformation takes place with CuCl as catalyst, N-methylpiperidine as additive, and t-BuOK as base in anhydrous DMF
                                    摘要描述了一种有效的
铜催化串联反应,可从容易获得的原材料合成 thiazol-2(3H)-one 结构。该协议提供了一种具有成本效益的方法,以可接受的产率获得大量含氮和
硫的杂环。以CuCl为催化剂,
N-甲基哌啶为添加剂,t-BuOK为碱,在无
水DMF为溶剂中进行转化。图形概要
