Abstract

The reaction of chromone-derived cyclic Morita-Baylis-Hillman alcohols with amines catalyzed by In(OTf)(3) in a one pot process was developed for the convenient and efficient synthesis of 2-substituted-3-aminomethylenechromans. The tandem allylic amination/chromen ring-opening/Michael cyclization reactions were involved in this protocol.
