The electrophilic alpha-alkylation of ketones with alcohols was accomplished by a [Ru(DMSO)(4)]Cl-2 catalyzed process, water being the only wasted material. The reaction can be successfully governed to produce either the expected ketones or their related alcohols only by changing the reaction conditions. When 2-aminobenzyl alcohol was used, a cyclization process took place to yield 2,3-disubstituted quinolines. (c) 2005 Elsevier Ltd. All rights reserved.

Intramolecular cyclodehydration of 3-arylpropionic acids catalyzed by heteropoly acids was investigated for the first time. Several 3-arylpropionic acids were refluxed and dehydrated in chlorobenzene in the presence of 0.2 equivalent of heteropoly acids, and 1-indanones were obtained in good yield. At the same time, intermolecular Friedel-Crafts acylation were observed in this experiment.
