Abstract

Abstract Ethyl 3, 5-diaryl-1H-pyrrole-2-carboxylates have been synthesized in good yields from ethyl 2-nitro-5-oxo-3, 5-diarylpentanoates by treatment with triethylphosphite under microwave irradiation. The integrity of the mechanism proposed has been augmented by 31 P NMR and EIMS experiments.
