Short Note: Ethyl 4,4''-Difluoro-5'-hydroxy-1,1':3',1''-terphenyl-4'-carboxylate
Molbank 2011, 2011(4), M745; doi:10.3390/M745 - published online 23 November 2011
Show/Hide AbstractAbstract: A simple and novel route for the synthesis of new terphenyl derivative as well as oxidative aromatization of α,β-unsaturated cyclohexenone to the corresponding phenol derivative is developed. The present work involves the condensation of ethylacetoacetate with 4,4'-difluoro chalcone followed by the aromatization using chloramine-T in acetic acid to yield the title compound (3). The synthesized compound (3) is well characterized by IR, NMR, LCMS and elemental analysis.
