  Studies on arylfuran derivatives

  摘要：

  Arylfurylpropenones 3 were synthesized by Claisen-Schmidt condensation of arylfurfurals 1 with various substituted acetophenones 2. Cyclocondensation of these arylfurylpropenones 3 with hydrazine hydrate and phenylhydrazine furnished 1H-pyrazolines 4 and N-phenylpyrazolines 6, respectively. In order to study the structure-activity relationships, pyrazolines 4 were converted into their N-acetyl derivatives 5. The antibacterial properties of the new pyrazoline derivatives were studied.
