Synthesis of some new azoles and azines and their condensed derivatives

Ethyl (2,5-Dimethylphenyl) pyruvate (2) condensed with o-phenylenediamine, ethylenediamine, semicarbazide and thiosemicarbazide and gave quinoxaline derivative (3), dihydropyrazine derivative (9) and 1,2,4-triazine derivatives (10, 11) respectively. Compound (3) reacted with phosphorous pentasulphide, polyphosphoric acid, semicarbazide hydrochloride and phenylisothiocyanate yielded thienoquinoxaline derivative (4), furoquinoxaline derivative (5), semicarbazone derivative (6) and pyrrole derivative (15) respectively. Reaction of (2) with hydrazines and malononitrile afforded the arylpyrazole derivatives (12a, b) and pyrane derivative (13) respectively. Hetrocyclization of compound (6) afforded thiadiazole and selenodiazole derivatives (7), (8).
