auxiliary, with methyl acrylate is described. Various carboxamides with a number of functional groups were compatible with this reaction to afford, regioselectively and in moderate yield, (E)-3-methyleneisoindolin-1-one derivatives bearing an alkyl(aryl)thio group. A palladium(II)-catalyzed olefination/annulation of aryl carboxamides, assisted by an N, S-bidentate auxiliary, with methyl acrylate is described
