overall excellent yields (up to 98%) with high enantioselectivities (up to 96 : 4 er). This approach not only has overcome the challenges in constructing axially chiral five-five-membered heterobiaryls, but also represents a new application of the C3-umpolung reactivity of 2-indolylmethanols in asymmetriccatalysis. More importantly, this class of axially chiral 3,3'-bisindoles can undergo a variety of
