  DOI：10.1080/00397919608004628

  日期：1996.9

  Reaction of 2-methylchromone (2) with phenylhydrazine provides 3-methyl-5-(o-hydroxyphenyl)-1-phenylpyrazole (6) as a major product. In contrast under similar conditions, heterocyclhydrazines (8a-c) yield exclusively 5-ethyl-3-(o-hydroxyphenyl)-1-heterocyclylpyrazoles (9a-c). The structural assignments are based on an unambiguous synthesis and an analysis of NMR (H-1 & C-13) spectral data,

  日期：——

  novel and efficient cerium-catalyzed tandem oxidation and intermolecular ring cyclization of vicinal diols with hydrazones has been achieved for the regioselective synthesis of pyrazole derivatives. The corresponding 1,3-di- and 1,3,5-trisubstituted pyrazoles were obtained in moderate to excellent yields. The reaction has the advantages of mild conditions, easily available starting materials, broad substrate
