three-component coupling reaction between thioformamides and organolithium and Grignard reagents was developed. The generality of the process has been demonstrated by using various combinations of reactants and reagents. Information about the mechanism of the reaction has come from 1H and 13C NMR spectroscopic detection of the key intermediate. The LiS group in the intermediates generated by addition
开发了硫代甲酰胺与有机锂和格氏试剂之间的高效三组分偶联反应。已通过使用反应物和试剂的各种组合证明了该方法的通用性。关于反应机理的信息来自关键中间体的 1H 和 13C NMR 光谱检测。通过将有机锂试剂加入硫代甲酰胺而生成的中间体中的 LiS 基团用作离去基团。在这些反应中形成的固体副产物,配制成 [LiSMgBr],可用作硫醇化剂,将酰氯转化为硫代酸和硫代酸酐。
