Abstract

AbstractAza‐ortho‐quinone methides allow the straightforward asymmetric synthesis of natural‐product‐inspired indole scaffolds possessing a quaternary stereocenter. Our approach provides access to diverse communesin and spiroindoline derivatives with high enantioselectivity under mild reaction conditions. Predictable substitution patterns are found to be the key to our regiodivergent protocols.
