Abstract

Alkylation of secondary sulfonamides by alkyl halides or alcohols (Mitsunobu reaction) is an efficient method for secondary amines preparation. However, its application to parallel chemistry is often difficult due to partial reaction. In this Letter, we propose a fluorous technique to bypass this problem. Thus, o-nitrobenzenesulfonamides were prepared and alkylated in parallel (Fukuyama method) with various alkyl halides or alcohols. Depending ...
