Abstract Reaction of sulfur ylides with a series of aryl substituted chiral nonracemic sulfinyl imines afforded the corresponding aziridines in good yields with good stereoselectivity. The sulfur ylides were generated by the thermally induced decarboxylation of carboxymethylsulfonium betaines. A drop in the diastereomeric ratio was observed when going from electron-deficient to electron-releasing aryl
摘要 硫叶立德与一系列芳基取代的手性非外消旋亚磺酰亚胺反应,以良好的产率和良好的立体选择性得到相应的氮丙啶。硫叶立德是通过羧甲基锍甜菜碱的热诱导脱羧作用产生的。当从缺电子到释放电子的芳基取代亚胺时,观察到非对映体比率下降。涉及羧甲基锍甜菜碱功能性脱羧的 S-亚甲基氮丙啶化反应在反应方案、转化水平和范围方面具有优势,是对现有技术的补充。
