摘要：

Enantioselective addition of various aryllithium reagents to aromatic imines was catalyzed (20 mol-%) by readily accessible 1,2-diamines to afford a wide range of protected diarylmethylamines in up to 94% enantiomeric excess. Furthermore, the absolute configuration of these arylation products was determined by using X-ray crystallography. ((c) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005).
