A metal‐free method for reduction of cyclic N‐sulfonyl ketimines catalyzed by B(C6F5)3, using commercially available methylphenylsilane as a reducing reagent under mild conditions has been developed. This reductive method was effective, not only providing the expected cyclic N‐Sulfonamides in good to excellent yields, but also showing good functional‐group tolerance.
开发了一种无金属的方法,在温和的条件下,使用市售的甲基苯基硅烷作为还原剂,还原由B(C 6 F 5)3催化的环状N-磺酰基酮亚胺。这种还原方法是有效的,不仅可以提供预期的环状N-磺酰胺类化合物,而且产率很高,而且显示出良好的官能团耐受性。
