A benzimidazole ring formation strategy for the synthesis of axially chiral N-arylbenzimidazoles by means of chiralphosphoricacid catalysis is presented. Two sets of conditions were developed to transform two classes of 2-naphthylamine derivatives into structurally diverse N-arylbenzimidazole atropisomers with excellent chemo- and regioselectivity as well as high levels of enantiocontrol.
