The nucleophilic addition of imidazole to cyanoacetylene alcohols is regioselective and leads to the formation of β-hydroxyalkyl-β-imidazolylacrylonitriles, which undergo cyclization to dihydrofurans in the presence of bases (sodium hydroxide, potassium hydroxide).The E isomer takes part in cyclization.The reaction is accompanied by the elimination of imidazole and the formation of lactone.
