Zusammenfassung:An efficient and rapid synthesis of new heterocyclic compounds via reactions of 1,3-diphenyl-1 H -pyrazole-4-carbaldehyde thiosemicarbazone with some carbon electrophiles, namely dimethyl acetylenedicar-boxylate, maleic anhydride, and ω-bromoacetophenone, under microwave irradiation has been developed. The structure of the synthesized compounds was confirmed by their analytical and spectral data.
