source, a KF-catalyzed strategy was employed for the direct thiomethylation of carboxylic acids with DMSO for the preparation of methyl thioesters. In this process, a wide range of methyl thioesters were obtained in moderate to excellent yields. This novel strategy features the first use of DMSO as a methylthiolating agent for the construction of methyl thioesters, transition metal-free conditions, inexpensive
以二甲亚砜(DMSO)为甲硫源,采用KF催化策略将羧酸与DMSO直接硫甲基化,制备甲基硫酯。在此过程中,以中等至优异的收率获得了多种甲基硫酯。这一新颖策略的特点是首次使用 DMSO 作为甲基硫醇化剂来构建甲基硫酯、无过渡金属条件、廉价试剂、易于后处理、广泛的底物范围和可持续性。此外,该过程可以很容易地扩展到克级。
