Abstract

Recent synthetic applications of quinone imines1 and bisimines2 have focused on nucleophilic additions promoted by both acids and bases. 3 These reactions require the use of stable N-arylsulfonyl derivatives of quinone imines to avoid decomposition, which occurs with more labile protecting groups. However, the strongly acidic conditions necessary to remove the sulfonyl group, 4 after transformation of the quinone imine, limit their synthetic ...
