3-Pyrrolecarboxylates 4 can be prepared from α-nitroolefins 1 and acetoacetates 2 by two methods: (a) 1 and 2 react to give 4,5-dihydro-5-methyleneamino-3-furancarboxylates 3 which are hydrolyzed, (b) the nitronic acids 8, adducts of 1 and 2, yield with different reduction agents the heterocycles 4.
