An Efficient Method for the Preparation of Monoalkylated Sulfonamides from Unsubstituted Sulfonamides and Alkyl Diphenylphosphinites by Oxidation-Reduction Condensation Using Trimethylsilylmethyl Azide

摘要

An efficient method for monoalkylation of unsubstituted Sulfonamides was established by using alkyl diphenylphosphin-ites,Sulfonamides and trimethylsilylmethyl azide and the mono-alkylated Sulfonamides were afforded in good yields under neutral conditions.
