RAPID AND EFFICIENT SYNTHESIS OF 2-[3-CYANO-4-(2-ARYLIDEN)-5, 5-DIMETHYL-5H-FURAN-2-YLIDENE]-MALONONITRILE UNDER FOCUSED MICROWAVE IRRADIATION
摘要:
New biological potential furan-2-ylidenemalononitriles (IIIa-j) were synthetised efficiently by one-pot condensation under focused microwave from starting and easy available compounds.

5,5-Substituted 2-imino-4-methyl-2,5-dihydrofuran-3-carbonitriles reacted with aromatic aldehydes to give the corresponding 5,5-substituted 2-imino-4-(2-R-vinyl)-2,5-dihydrofuran-3-carbonitriles. The latter were converted into hydrochlorides which were hydrolyzed to 3-cyano-4-(2-R-vinyl)-2,5-dihydrofuran-2-ones whose condensation with malononitrile afforded dicyanomethylidene derivatives.
