The silver carbonate‐catalyzed direct CH phosphorylation of indoles in the presence of magnesium nitrate is described. The reaction affords selectively phosphonoindoles in moderate to good yields through a radical process. This protocol provides an efficient and general method for the preparation of 2‐ and 3‐phosphorylated indoles.

Palladium-catalyzed annulation of 1-alkynylphosphine sulfides with 2-iodoanilines followed by desulfidation affords 3-substituted 2-indolylphosphines. This annulation/desulfidation sequential protocol offers a conceptually new approach to bulky heteroarylphosphines.

An organocatalytic enantioselectivesynthesis of axiallychiral 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 axiallychiral N,N′-bisindoles and shows the successful application of such skeletons in medicinal and synthetic
