A general synthesis of chiral 4,5-dihydro-3H-dinaphthophosphepines 1a-g is described. The resulting ligands represent a new class of monodentate chiral phosphines. First applications of 1a-g in the rhodium-catalyzed asymmetric hydrogenation of unsaturated carboxylic acid derivatives demonstrate the
