Abstract
Abstract 2-Oxo-2H-chromenylpyrazolecarboxylates (8a–h and 12a–zb) have been synthesized by [3+ 2] cycloaddition of 2H-chromenophenylhydrazones (7a–h and 11a–w) with diethyl/dimethylbut-2-ynedioates. Phenylchromeno [4, 3-c] pyrazol-4 (1H)-ones (13i–n) were prepared from corresponding phenylhydrazones (7a–h) with catalytic amount of piperidine in presence of pyridine as a solvent at 100 C. All the synthesized compounds ( ...
