A transition-metal-free approach to synthesize unsymmetrical disulfides is reported that relies on a K2CO3-promoted one-pot reaction of thiosulfonates, thiourea and alkyl halides under mild conditions. The protocol tolerates a wide range of substrates, leading to various types of unsymmetrical disulfides in moderate to excellent yields. More importantly, the late-stage modification of natural products
据报道,一种合成不对称二硫化物的无过渡金属方法依赖于在温和条件下K 2 CO 3促进的硫代磺酸盐、硫脲和烷基卤化物的一锅反应。该协议容忍广泛的底物,导致各种类型的不对称二硫化物,产量中等至极好。更重要的是,还实现了天然产物和药物分子的后期修饰。
