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 Isomeric Δ2-Pyrazolines
Thakare, V. G.,Wadodkar, K. N.
, p. 610 - 612 (2007/10/02)
2'-Hydroxychalkones (I) react with hydrazine hydrate in ethanol to give 5-aryl-3-(2-hydroxyphenyl)-Δ2-pyrazolines (II) while in acetic acid the corresponding 5-aryl-1-acetyl-3-(2-hydroxyphenyl)-Δ2-pyrazolines (III) are obtained contr
Synthesis and Antimicrobial Activity of Hydroxyarylpyrazoles
Sharma, T. C.,Bokadia, M. M.,Reddy, N. J.
, p. 228 - 229 (2007/10/02)
Hydroxyarylpyrazolines (III) and Pyrazoles (IV) have been synthesized.Compounds IVa and IVd exhibit marked antifungal activity against A. niger, C. albicans, C. neoformans, T. mentagraphytes and M. canis whereas compound IVc shows activity against the last three fungi.None of the compounds shows any noteworthy antibacterial activity against Staphy. aureus, Staphi. typhi and Esch. coli even at 100 μg/ml.
