Indole-based atropisomers are a very important class of axially chiral compounds. However, the atroposelective synthesis of axially chiral 2-arylindole remains largely unexplored. In this study, we report the successful synthesis of atropisomeric 2-arylindoles using directamination of indoles with p-quinonediimines in the presence of chiral phosphoric acid as a catalyst. Quinonediimine acts as an
