Enantioselective formation of all-carbon quaternary stereocenters from indoles and tertiary alcohols bearing a directing group.

Described is an efficient catalytic asymmetric intermolecular C-C bond-formation process to generate acyclic all-carbon quaternary stereocenters. The reactions overcome the unfavorable steric hindrance around reactive centers, and the competitive elimination (E1), to form a range of useful indole products with excellent efficiency and enantioselectivity.
