Vinylthio phthalimides 1, synthesized by addition of phtalimidosulphenyl chloride to some alkynes, react with 2 equivalents of lithiumtriethylboron hydride to give vinylthio substituted thiiranes 3 with high degree of diasteroselectivity. The reaction of 1 with 1 equivalent of the same hydride affords divinyl disulphides 6 which resulted to be intermediates in the formation of thiiranes 3 since the
通过将邻苯二亚甲基磺酰氯加成至某些炔烃而合成的乙烯基硫代邻苯二甲酰亚胺1与2当量的氢化三乙基硼氢化锂反应,可得到高度非对映选择性的乙烯基硫代取代的噻喃3。的反应1与1个当量的氢化物相同,得到二乙烯基二硫化物6这导致为在形成硫杂丙环的中间体3,因为反应6与1当量的氢化lithiumtriethylboron得到episulphides 3中相同的非对映异构混合物。提出了这些反应的机制。
