The chemical behavior of 4,9-dimethoxy-5-oxo-5H-furo[3,2-g]chromene-6-carbonitrile (1) was investigated toward some acyclic and cyclic active methylene ketones namely acetylacetone, ethyl acetoacetate, ethyl benzoylacetate, acetoacetanilide, dimedone, indanedione, pyrazolidine-3,5-dione and 5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one, barbituric acid and 1-allylthiobarbituric acid, and hippuric acid. A variety of novel heteroannulated furochromenopyridines were efficiently synthesized through a cascade reactions between 4,9-dimethoxy-5-oxo-5H-furo[3,2-g]chromene-6-carbonitrile (1) and the carbon nucleophilic reagents. Structures of the new products were inferred based on their analytical and spectral data.
