ulfur ylides are among the most significant and widely applied chemical reagents participated in the field of organic synthetic chemistry. The chemistry of this type of reagents has evolved dramatically over the past 50 years since the pioneering work of Johnson, Corey and Chaykovsky in the 1960s as the well-known Johnson-Corey-Chaykovsky reaction. Based on that, sulfur ylides can react with polar substrates, for example, aldehydes, 3 ketones, 4 imines 5 and electron-deficient alkenes to produce a wide range of significant small-ring molecules such as epoxides, aziridines, cyclopropanes and so on .
