The base catalyzed addition of sterically hindered 1,3-diketones to the activated multiple bond of ethyl acrylate and 4-methyl-4-methoxy-1-phenylpent-2-yne-1-one has been studied. The addition of methyl(2-propenyl)ketone is partially accompanied by intramolecular cyclization of the resulting adduct.
