Abstract

Sulfonyl groups have had a long history in protection of amines and other nitrogeneous functionality. 1 One of the most attractive features of sulfonamides, their stability to a wide array of reaction conditions, has commonly proven a liability, since removal is oftentimes problematic in highly functionalized, sensitive substrates. In recent years the arsenal of N- sulfonyl protecting groups has been improved by addition of new varieties amenable to ...
