1‐ N ‐Alkyl‐1‐azapenta‐1,3‐dienes 2 smoothly reacted with various mesoionic oxazolones 1 to afford 3,4‐di‐hydro‐2‐pyridones 3 in excellent yields and there was no evidence for the formation of any products arising from the cycloaddition on the carboncarbon double bond or on the azomethine function.
