Methyl (ethyl) 5-(2'-furyl) isoxazole-3-carboxylate (3a and 3b) were prepared from methyl (ethyl) 2-furoylpropiolates with hydroxylamine, respectively. Methyl (ethyl) 5-(2'-furyl) pyrzaole-3-carboxylates (10a and 10b) were formed by the condensation of methyl (ethyl) 2-furoylpropiolates with hydrazine hydrate. The corresponding 5'-nitro furan derivatives (4a and 11b) were obtained in usual manner, and the each position of nitro group of the furan rings was confirmed by the nuclear magnetic resoance and infrared spectral data.
