The furan-2-ylidene acetates (3a-d), obtained from the furan-2,3-diones (1a-b) and methyl/ethyl (triphenylphosphoranylidene)- acetates (2a-b), were converted via the Michael type reactions with 2,3-diaminopyridine and its derivatives (4a-c) into the corresponding pyrrol-2-ylidene-acetates (5a-j) in moderate yields (45-94%). Structures of these compounds were determined by the IR, NMR, elemental analysis, and X-ray diffraction method.

The Wittig reaction of 2,3-dihydro-4-(4-methoxybenzoyl)-5-(4-methoxyphenyl)-furan-2,3-dione (1) with methyl (triphenylphosphoranylidene)acetate (2) stereo- and regioselectively afforded methyl (Z)-[2,3-dihydro-4-(4-methoxybenzoyl)-5-(4-methoxyphenyl)-3-oxofuran-2-ylidene]acetate (3) in good yield. The reactions of 3 with primary amines (4a-k) gave corresponding 1-substituted 2,3-dihydro-1H-pyrrol-3-ones (5a-k).
