Three-component Ugi–Smiles couplings of cyclic imines
摘要:
Cyclic imines react with isocyanides and electron-deficient phenols to afford N-aryl piperidines and pyrrolidines in good yields (Ugi-Smiles couplings of cyclic imines). The starting imines were formed by oxidation with N-chlorosuccinimide followed by a base-induced dehydrochlorination. (C) 2009 Elsevier Ltd. All rights reserved.
