Microwave enhanced green synthesis of 2-pyrazolines, isoxazolines and cyclohexenones
Al-Bogami, Abdullah S.,Alkhathlan, Hamad Z.,Saleh, Tamer S.
, p. 6427 - 6433 (2013/07/26)
Hydroxy chalcones undergo simple cyclizations with phenylhydrazine to afford 2-pyrazolines under microwave irradiation in the presence of glacial AcOH as cyclizing agent, also undergo simple cyclizations with hydroxylamine to afford 2-isoxazolines under m
Synthesis of pyrazoline and isoxazoline in triethanolamine medium
Agrawal, Nitin N.,Soni
, p. 2700 - 2701 (2007/10/03)
Reactions of chalcones 1a-u with phenylhydrazine and hydrazine hydrate give pyrazolines 2a-u and with hydroxylamine hydrochloride yield isoxazolines 3a-c in triethanolamine medium. The structures of products are established by melting points, chemical studies and spectral data (IR and 1HNMR).
SYNTHESIS OF SOME ISOMERIC PYRAZOLES
