this report, the combination of masked inorganic sulfur and dimethyl carbonate was designed to achieve thiomethylated cross coupling of aryl chlorides. Remarkably, this powerful strategy realized thiomethylation of nucleosides bearing unprotected ribose, chloride-containing pharmaceuticals with late-stage coupling, and herbicides possessing multiple heteroatoms and steric hindrance. Moreover, this protocol
在本报告中,设计了掩蔽的无机硫和碳酸二甲酯的组合,以实现芳基氯的硫代甲基化交叉偶联。值得注意的是,这种强有力的策略实现了带有未保护核糖的核苷的硫代甲基化,具有后期偶联作用的含氯化物的药物以及具有多个杂原子和空间位阻的除草剂。而且,该方案实际上适用于具有较低催化负载和较高产率的多克级合成。
