|Abstract:||The condensation of a series of aromatic ketones with aromatic aldehydes under aldol conditions affords 1-aryl-3-(substitutedphenyl/phenyl furanyl/thienyl)-2-propen-1-ones 1. The resulting propenones undergo facile and clean cyclization with hydrazine and substituted hydrazine derivatives to yield 3-aryl-5-(substitutedphenyl/phenylfuranyl/thienyl)-2-pyrazolines 2. This reaction is carried out in the presence of Amberlyst–15 catalyst to afford the above pyrazolines 2 in considerably good yield. All the synthesized compounds have been characterized by spectral studies.|
