1‐Ethoxy‐1,3‐butadienes by Wittig Alkenylation of 3‐Ethoxyacroleins 2‐Alkyl‐1‐ethoxy‐1,3‐butadienes 3 as donor activated 1,3‐diene components for [4+2] cycloadditions are prepared by Wittig alkenylation of 2‐alkyl‐3‐ethoxyacroleins 1 . The title compounds react with maleic anhydride to give crystallized 2‐alkyl‐3‐ethoxy‐1‐cyclohexene‐4,5‐dicarboxylic acids 4 upon hydrolysis of the primary adduct.
