Reaction of 3-aryl-1-(benzofuran-2-yl)-2-propen-1-ones 3a–c with malononitrile in the presence of sufficient amount of sodium alkoxide in the corresponding alcohol proceeds in a regioselective manner to afford 2-alkoxy-4-aryl-6-(benzofuran-2-yl)-3-pyridinecarbonitriles 4–37, which also obtained by treating ylidenemalononitriles 6a–q with 2-acetylbenzofuran 1 in the presence of sufficient amount of
