SuFEx reactions, in which an S-F moiety reacts with a silyl-protected phenol, have been developed as powerful click reactions. In the current paper we open up the potential of SuFEx reactions as enantioselective reactions, analyze the role of Si and outline the mechanism of this reaction. As a result, fast, high-yielding, "Si-free" and enantiospecific SuFEx reactions of sulfonimidoyl fluorides have
SF部分与甲硅烷基保护的苯酚反应的SuFEx反应已被开发为强大的点击反应。在本文中,我们开拓了SuFEx反应作为对映选择性反应的潜力,分析了Si的作用并概述了该反应的机理。结果,已经开发出快速,高产率,“无硅”和对映体特异性的磺酰亚胺基酰氟SuFEx反应,并通过实验和理论方法证明了它们的机理,从而产生了手性产物。
