The solvent-free sulfur-mediated reactions of phosphinic chlorides with alkyl diamines were developed for the practical synthesis of unknown phosphoryl-substituted 4,5-dihydro-1H-imidazoles, 1,4,5,6-tetrahydropyrimidines, and thioamides. Their good tolerance to functional groups, broad substrate scope, and easy scalability were shown. The chemoselective preparation of a variety of phosphoryl-substituted
已开发出无溶剂的硫代氯化物与烷基二胺的无溶剂硫介导反应,用于实际合成未知的磷酰基取代的4,5-二氢-1 H-咪唑,1,4,5,6-四氢嘧啶和硫代酰胺。显示了它们对官能团的良好耐受性,广泛的底物范围和易扩展性。多种磷酰基取代的双(硫代酰胺)的化学选择性制备是通过调节溶剂来完成的。
