Chiral Phosphoramide‐Catalyzed Enantioselective Synthesis of 2,3′‐Diindolylarylmethanes from Indol‐2‐yl Carbinols and Indoles.

The first asymmetric addition of indol carbinols (I) with indol derivatives (II) and (IV) catalyzed by a BINOL-derived phosphoramide affords title compounds (III) and (V) in high yields as well as high enantioselectivities.
