Abstract

Products of Michael condensation containing a 1-phenyl-2-nitroethyl residue in the 4 position of the heteroring are formed in high yields in the reaction of equimolar amounts of 4-methyl-,4-ethyl-, 4-isopropyl-, 4-butyl-, 4-isoamyl-, and 4-phenyl-1, 2-diphenyl-3,5-dioxopyrazolidines and 1,2-diphenyl-3,5-dioxopyrazolidine with β-nitrostyrene under basic catalysis conditions. 1,2-Diphenyl-3,5-dioxopyrazolidine adds two equivalents of β-nitrostyrene when a twofold excess of the latter is present.
