Popis: A regioselective inverse-electron-demand hetero-Diels–­Alder reaction of in situ generated 1,2-diaza-1,3-dienes with methoxyallene is reported. These Lewis and Bronsted acid free reactions benefit from operational simplicity and allow access to synthetically valuable 5-methylene-6-methoxy-1,4,5,6-tetrahydropyridazines in high yields.
