diphenylvinyl sulfonium triflate with nucleophiles and either aldehydes or imines gives epoxides and aziridines, respectively, in a three-component reaction. cis-Aziridines could be formed in good diastereomeric ratio, and the selectivity was correlated to the reactivity of the imine. This represents the first study of cis/trans selectivity in the reactions of imines with non-stabilized sulfur ylides.
二苯基乙烯基锍三氟甲磺酸盐与亲核试剂和醛或亚胺偶联,在三组分反应中分别生成环氧化物和氮丙啶。顺式氮丙啶可以以良好的非对映体比例形成,选择性与亚胺的反应性相关。这是对亚胺与不稳定硫叶立德反应中顺式/反式选择性的首次研究。
