Synthesis of some thienyl-substituted α,β-unsaturated ketones containing a nitro group

A method for the condensation of nitroformylthiophenes with ketones of the aromatic and heterocyclic series by means of ammonium acetate in glacial acetic acid was developed. The method makes it possible to obtain thienyl-substituted , -unsaturated ketones with a nitro group in the heterocyclic ring.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 8, pp. 1048–1049, August, 1980.
