[Reaction: see text] A simple procedure to obtain N-sulfonyl imines involving the condensation of carbonyl compounds with p-tolyl or tert-butyl sulfinamides followed by oxidation with m-CPBA of the resulting N-sulfinylimines is reported. The method is applicable to aldehydes (aliphatics and aromatics) and ketones (diaryl, dialkyl, and aryl alkyl), even those containing enolizable protons. It also does
[反应:见正文]报告了一种简单的获得N-磺酰基亚胺的方法,该方法包括羰基化合物与对甲苯基或叔丁基亚磺酰胺的缩合,然后用m-CPBA氧化所得N-亚磺酰亚胺。该方法适用于醛类(脂族和芳族化合物)和酮类(二芳基,二烷基和芳基烷基),甚至是那些含有可烯化质子的酮。它也不会影响C = N或C = C双键,并且不会差向α-立体异构中心。
