and diastereoselective rhodium-catalyzedintermolecular hydroacylation reaction of salicylaldehydes with norbornenes is reported in which the corresponding aryl ketones are obtained in high diastereomeric and moderate enantiomeric excesses. It was found that monodentate phosphoramidite ligands gave rise to endo products, while bidentate phosphine ligands catalyzed the reaction to form exo products predominantly
