| Abstract/Summary |
Condensation of 3-formylchromenes with pyrazolinylquinolinone afforded the chromenylmethylenepyrazolinones. The reactivity of these products towards different bidentate heteroatom nucleophiles, viz. hydrazine, quinolinylhydrazine, hydroxylamine, ketene-S,S-acetal, sulfanylacetic acid, cyanthioacetamide, thiourea, guanidine, thiobarbituric acid, 2-aminothiophenol, and 4-aminotriazole-3-thiol, was investigated at different mole ratios and reaction conditions. Versatile novel heteropolycyclic systems were obtained as substituents at the 3-pyrazolinylquinolinone moiety derived from nucleophilic ring opening of chromene.
