catalyst-free synthetic methods for β-keto dithiocarbamates, thiazolidine-2-thiones, and thiazole-2-thiones via the multicomponent reaction of CS2, amines, and sulfoxonium ylides have been described. The β-keto sulfoxonium ylides furnished β-keto dithiocarbamates in the presence of CS2 and secondary amines, whereas primary amines afforded thiazolidine-2-thiones or thiazole-2-thiones after dehydration in an acidic
已经描述了通过 CS 2 、胺和氧化硫叶立德的多组分反应合成 β-酮基二硫代氨基甲酸酯、噻唑烷-2-硫酮和噻唑-2-硫酮的简单、通用且无催化剂的合成方法。β-酮基亚砜叶立德在 CS 2和仲胺存在下生成 β-酮基二硫代氨基甲酸酯,而伯胺在酸性环境中脱水后生成噻唑烷-2-硫酮或噻唑-2-硫酮。反应过程简单,底物范围广,官能团耐受性好。
