for synthesis of 2H-pyran-3,4-dicarboxylates using the three-component reaction of dithiocarbamates, dialkyl acetylenedicarboxylates, and isocyanides in solvent-free conditions is described. In these reactions, synthesis of dithiocarbamates is possibly based on the one-pot reaction of secondary amines, CS2, and alkyl halides in solvent-free conditions without using a catalyst. The mild reaction conditions
描述了一种在无溶剂条件下使用二硫代氨基甲酸酯,乙炔基二羧酸二烷基酯和异氰酸酯的三组分反应合成2 H-吡喃-3,4-二羧酸酯的有效方法。在这些反应中,二硫代氨基甲酸酯的合成可能基于仲胺,CS 2和烷基卤化物在无溶剂条件下的一锅反应,而无需使用催化剂。温和的反应条件和高产率的反应显示了这些方法的良好合成优势。
