Abstract

Abstract The first example of KF/Al 2O 3-catalyzed versatile hetero-Michael addition reaction of nitrogen, oxygen, and sulfur nucleophiles was developed for facile preparation of organic compounds of widely different structures. In contrast with the existing methods using many acidic catalysts, this method is very general, simple, high-yielding, environmentally friendly, and oxygen and moisture tolerant.
