As a result of our recent investigations into the N-functionalization of sulfoximines, an iron-catalyzed dealkylative acylation of N-alkylsulfoximines has been developed. This process involves a Polonovski-type dealkylation of an N-alkylated sulfoximine to afford a reactive intermediate that is trapped in the presence of a suitable aldehyde or anhydride to afford N-acyl- and N-aroylsulfoximine derivatives
由于我们最近对亚砜亚胺的 N-官能化的研究,开发了一种铁催化的 N-烷基亚砜亚胺的脱烷基酰化。该方法涉及 N-烷基化亚砜亚胺的 Polonovski 型脱烷基化,以提供反应性中间体,该中间体在合适的醛或酸酐存在下被捕获,以在一锅中提供 N-酰基-和 N-芳酰基亚砜亚胺衍生物。随后在酸性条件下裂解酰基或芳酰基会产生具有合成价值的 NH-亚砜亚胺。
