Synthesis and Comparison of the Biological Activities of Derivatives of 3,5-Diphenyl-2H-pyrano[2,3-b] Quinolin-2-one

Abstract

Synthesis of a series of title compounds (3) and its unknown derivatives is reported by the condensation of sodium salt of methoxy phenylacetic acid with 3-formyl-4-phenyl-2-quinolones (2). The compounds (2) in tum were obtained from their respective chloroquinolines (1). Structures of all the products have been established by spectral and elemental analysis data. Biocidal activities have been tested in vitro.
