Domino Heck-aza-Michael reactions: efficient access to 1-substituted tetrahydro-beta-carbolines.
A simple and efficient palladium-catalyzed domino reaction for the synthesis of a series of C1-substituted tetrahydro-beta-carbolines is described. This domino process involves a Heck reaction at the indole 2-position of a halogenated tryptamine precursor, followed by intramolecular aza-Michael addition.
