A novel approach to the synthesis of 2-aryl propionates
Patil,Wadia
, p. 2821 - 2827 (2007/10/03)
A two step conversion of phenyl glyoxylates to 2-aryl-propionates has been accomplished. Esters of phenylglyoxylic acid have been converted to corresponding β,β-dichlorostyrenes. These on further reduction gave esters of 2-arylpropionic acids.
