Abstract
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.
