Abstract

A series of some novel 5-aryl-3-(4-hydroxy-6-methyl-2H-pyran-2-oxo-3-yl)-1-heteroaryl pyrazolines have been prepared by the reaction of 3-cinnamoyl-4-hydroxy-6-methyl-2H-pyran-2-ones i.e., chalcone analogues of dehydroacetic acid (DHA) with various heteroaryl hydrazines and converted to corresponding pyrazoles with iodobenzene diacetate in good yields.

Keywords

Chalcone Dehydroacetic acid Heteroaryl hydrazines Pyrazolines Iodobenzene diacetate Pyrazoles.
