A simple and efficient chemoselective alkylation of phenols in polyfunctional aromatic compounds with different alkyl halides in the presence of K2CO3/TBAB is reported. The method is successful with various hydroxy aromatic acids or oximes possessing other functional groups. (c) 2007 Elsevier Ltd. All rights reserved.
