An organocatalytic enantioselective synthesis of axially chiral N,N′-bisindoles has been established via chiral phosphoric acid-catalyzed formal (3+2) cycloaddition of indole-based enaminones with 2,3-diketoesters. This study provides a new strategy for the highly selective synthesis of axially chiral N,N′-bisindoles and shows the successful application of such skeletons in medicinal and synthetic
