Vanadium-catalysed novel oxidation of arylacetic esters for the synthesis of arylglyoxylic esterst
Abstract
Direct synthesis of arylglyoxylic esters in excellent yields from inexpensive arylacetic esters is realised for the first time by the oxidation of activated methylene using vanadium pillared clay as the catalyst and tert-butylhydroperoxide as an oxidant.
