An efficient and interesting N-centered umpolung method has been disclosed to construct beneficial S–N bonds, furnishing N-sulfenylimines, which can readily be converted into the corresponding sulfonamide derivatives in a one-pot sequential operation. N-Sulfenylimines are potent intermediates in organic synthesis, whereas sulfonamides are of major molecular interest due to their rich biological activities
已经公开了一种有效且有趣的N中心 umpolung 方法来构建有益的 S-N 键,提供N -硫基亚胺,它可以在一锅顺序操作中轻松转化为相应的磺酰胺衍生物。 N-磺基亚胺是有机合成中有效的中间体,而磺酰胺由于其丰富的生物活性和在药物化学中的广泛适用性而备受分子关注。由于反应条件和设置简单,该方案显示出广泛且通用的底物范围,从而对N-硫基亚胺和磺酰胺的合成具有优异的官能团耐受性。针对这种独特的方法,提出了一种经过计算和实验支持的密度泛函理论(DFT)的便捷机制。
