  Microwave-assisted synthesis and antimicrobial evaluation of novel pyrazolines

  摘要：

  A series of 6-(5-aryl-4,5-dihydro-1H-pyrazol-3-yl)-2,2-dimethylchroman-7-ol and 6-(5-aryl-4,5-dihydro-1H-pyrazol-3-yl)-2,2-dimethyl-chroman-5-ol derivatives have been synthesized from the corresponding chalcones and hydrazine hydrate in the presence of sodium acetate under microwave irradiation involving the Michael addition followed by cycloaddition. All the newly synthesized 18 compounds were screened for their in vitro antimicrobial activity. Most of the compounds displayed very good to excellent antimicrobial activity in comparison to standard drugs streptomycin and nystatin.

  Crotaoprostrin, a chalcone not yet known as a plant constituent, was isolated from the aerial parts of the Indian medicinal plant Crotalaria prostrata. The structures of the chalcone polyarvin and the partially hydrogenated naturally occurring derivatives crotaramin, crotaramosmin, and crotin were confirmed by chemical synthesis.
