Iminothiocarbonyl ylides are generated by a sulfur ligand exchange reaction of sulfonium salts and undergo a 6π-electrocyclic closure and aromatization to trisubstituted thiazoles. Related carbonyl ylides preferred a 4π-electrocyclization.
亚氨基硫代羰基烷基化物是由sulf盐的硫配体交换反应生成的,并经过6π-电环封闭并芳构化为三取代的噻唑。相关的羰基酰化物优选4π-电环化。
