摘要

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 protocol was effective, not only providing the expected cyclic N-sulfonamides in good to excellent yields, but also showing good functional-group tolerance.
