To expand the toolbox for the synthesis of ortho-phenolic sulfilimines, sigmatropic rearrangements were introduced to the field of sulfilimine chemistry. Herein we report a N-H sulfenylation/[2,3]-sigmatropic rearrangement cascade reaction. This mild reaction enables commercially available thiols to serve as the sulfenylation reagent and generates water as the sole byproduct. Moreover, the reaction
为了扩展用于合成邻苯酚亚硫亚胺的工具箱,将σ重排引入亚硫亚胺化学领域。在这里,我们报告一个NH亚磺酰化/ [2,3] -sigmatropic重排级联反应。这种温和的反应使可商购的硫醇充当亚磺酰化试剂,并产生水作为唯一的副产物。此外,该反应具有广泛的底物范围,并且可以以克规模进行,具有优异的反应效率。
