Axially chiral compounds widely occur in natural products, biologically active molecules, ligands, and catalysts, and their efficient and enantioselective synthesis is highly desirable. Herein, we report a novel method for the atroposelective construction of axially chiral N-aryl benzimidazoles with chiral phosphoric acid as the organocatalyst via reaction of N1-(aryl)benzene-1,2-diamines with multicarbonyl compounds. The present method provided the target products in high yields (up to 89percent) with excellent enantioselectivity (up to 98percent ee).

Heteroleptic compounds containing phenylpyridine and phenylbenzimidazole are provided. The compounds may be used in organic light emitting devices, particularly as emissive dopants in the emissive layer of such devices.
