A simple method for the construction of propen-2-yl sulfones through cascade reactions of calcium carbide with arylsulfonylhydrazones using copper as a mediator is described. The salient features of this protocol are the use of readily available and easy-to-handle alkyne source, broad substrate scope, open-air condition, and simple operation procedure.
描述了一种简单的方法,该方法通过使用铜作为介质,通过电石与芳基磺酰基cascade的级联反应来构建丙烯-2-基砜。该协议的显着特征是使用易于获得且易于处理的炔烃源,广泛的底物范围,露天条件和简单的操作程序。
