An efficient synthesis and DNA binding interaction study of some novel heterocyclic fused-pyarzolequinolines: A potent antimicrobial agent

In the present paper, the synthesis of 3-(5-phenyl-4,5-dihydro-1H-pyrazol-3-yl)quinolin-2-ol (2a)/(3a) and 3-(2-hydroxyquinolin-3-yl)-5-phenyl-4,5-dihydro-1H-pyrazole-1 carbothioamide(4a) were prepared according to Claisen-Schmidt condensation, viacondensation of 2- hydroxyquinoline-3-carbaldehyde with ketones. Then finally, α, β-unsaturated ketone (3) reacts with hydrazine hydrate,...
