Abstract:  Nitration of methyl 3-(5-nitro-2-furyl)acrylate with fuming nitric acid afforded 5-nitro-2-furancarboxylic acid (II) as a main product (70%) and 5-nitro-2-furaldehyde (III) and methyl ester of 2-nitro-3-(5-nitro-2-furyl)acrylic acid /V as by-products. The nitration of methyl ester of / gave at — 10°C the corresponding methyl ester of IV in a 29% yield, whereas the nitration with a solution of N204 in CCl4 furnished methyl ester of IV even in a better yield. Both procedures led prevalently to the Z configuration of the ester of IV.
