Abstract

Novel 8-Benzyloxy-5-[2-(substituted-phenyl)-thiazol-4-yl]-1H-quinolin-2-one derivatives are synthesized by the cyclocondensation of substituted thiobenzamide and in-situ generated 8-benzyloxy-5-(2-bromo-acetyl)-1H-quinolin-2-one in the ethanol using simple one-pot multicomponent protocol under catalyst-free reaction conditions. All the products were screened for anti-tuberculosis (TB) activity against Mycobacterium tuberculosis H37Rv stains using L. J. medium conventional method and Compound 4h show good and Compound 4a, 4c, 4e, 4g, 4i, and 4j are also showing significant activity against M. tuberculosis.
