A new diamine ligand for asymmetric transfer hydrogenation (ATH) was discovered. The reductive cyclization of 2-acylarylcarboxylates was found to proceed highly stereoselective by the new Ru complex-catalyzed ATH and subsequent In situ lactonization under aqueous conditions. It enables efficient access to a wide variety of 3-substituted phthalides In enantiomerically pure form.
