Reactions of the diene 1‐benzyloxy‐2‐methoxy‐1,3‐pentadiene‐5‐ol in intramolecular Diels‐Alder reactions using maleic anhydride or fumaric acid ethyl ester is described. The new reactive diene is prepared starting from 3‐methoxypyridine. The structure of the diene was elucidated by a NOE nmr experiment.
