The efficient one-pot umpolung alpha-phenylation of ketones via N-alkenylisoxazolidine is described. When the various ketones are treated with triphenylaluminum prepared from phenylmagnesium chloride and AlCl3 in the presence of isoxazolidine, the desired products are obtained in good to moderate yield. This method is equivalent to a direct alpha-arylation reaction of carbonyl groups. (C) 2012 Elsevier Ltd. All rights reserved.
