sulfinamides, using Grignard, organolithium, or organozinc reagents to introduce the carbon fragment. Treatment of these primary sulfinamides with an amine in the presence of a hypervalent iodine reagent leads directly to NH-sulfonimidamides. This two-step sequence is straightforward to perform and provides a modular approach to sulfonimidamides, allowing ready variation of both reaction components, including
一种新的N-甲硅烷基亚磺胺试剂允许使用格氏试剂、有机锂或有机锌试剂引入碳片段,快速制备各种(杂)芳基、烯基和烷基伯亚磺酰胺。在高价碘试剂存在下用胺处理这些伯亚磺酰胺直接产生NH-磺酰亚胺。这种两步序列易于执行,并为磺胺类药物提供了模块化方法,允许对包括伯胺和仲胺在内的两种反应组分进行随时变化。
