methylthiotransfer process in organisms, and therefore its functionality is of paramount importance to living organisms. Several methods for the installation of the methylthio group in small molecules have been reported previously; however, procedures starting from unactivated alkenes are rare. Herein, we report a formal hydro/deuteromethylthiolation of alkenes by using dimethyl(methylthio)sulfonium trifluoromethanesulfonate
甲硫醚参与生物体内的甲硫基转移过程,因此其功能对生物体至关重要。先前已经报道了几种在小分子中安装甲硫基的方法。然而,从未活化的烯烃开始的程序很少见。在此,我们报告了烯烃的正式加氢/氘甲基硫醇化,使用二甲基(甲硫基)锍三氟甲磺酸盐作为刺激剂,硼氢化钠/氘化钠作为氢/氘源。该工艺代表了一种温和的、无过渡金属和无甲硫醇的路线,可从未活化的烯烃合成甲基硫醚。
