Abstract

Abstract The 1, 4-cycloaddition reaction of 4-phenyl-1, 3-oxazole to 2-propinyl benzoate and dimethyl butinedioate afforded the respective 3-furylmethyl benzoate (I) and 3, 4-bis (methoxycarbonyl) furan (II). These compounds served for the synthesis of 3- chloromethylfuran and 3, 4-bis (chloromethyl) furan, which afforded via Wittig reaction 3-(β- arylvinyl) furans III (aryl= 5-nitro-2-furyl (IIIa), 5-nitro-2-thienyl (IIIb), 1-methyl-4-nitro-2- ...
