The first catalytic asymmetric construction of 3,3 '-bisindole skeletons bearing both axial and central chirality has been established by organocatalytic asymmetric addition reactions of 2-substituted 3,3 '-bisindoles with 3-indolylmethanols (up to 98 % yield, all >95:5 d.r., >99 % ee). This reaction also represents the first highly enantioselective construction of axially chiral 3,3 '-bisindole skeletons, and utilizes the strategy of introducing a bulky group to the ortho-position of prochiral 3,3 '-bisindoles. This reaction not only provides a good example for simultaneously controlling axial and central chirality in one operation, but also serves as a new strategy for catalytic enantioselective construction of axially chiral 3,3 '-bisindole backbones from prochiral substrates.
