Abstract

Abstract Diethyl 5-isopropenyl-4, 5-dihydrofuran-2, 3-dicarboxylate 1a and methyl 5- isopropenyl-3-methoxy-carbonyl-4, 5-dihydrofuran-2-acetate 2a were prepared by cylization of diethyl 2-oxosuccinate or dimethyl 3-oxoglutarate with (E)-1, 4-dibromo-2-methyl-2- butene. Their chemical properties were studied.
