AgOTf‐Catalyzed Aza‐Diels–Alder Reactions of Danishefsky's Diene with Imines in Water

Abstract

Abstract Aza‐Diels–Alder reactions of Danishefsky's diene with imines in water took place smoothly in the presence of a catalytic amount of silver triflate to afford dihydro‐4‐pyridones in high yields. The silver triflate‐catalyzed three‐component reactions starting from aldehydes, amines, and Danishefsky's diene were also performed efficiently. In the three‐component reactions with benzaldehyde, the addition of a non‐ionic surfactant was found to be effective.
