Domino Heck−Aza-Michael Reactions: Efficient Access to 1-Substituted Tetrahydro-β-carbolines
摘要:
A simple and efficient palladium-catalyzed domino reaction for the synthesis of a series of Cl-substituted tetrahydro-beta-carbolines is described. This domino Process involves it Heck reaction at the indole 2-position of a halogenated tryptamine precursor, followed by intramolecular aza-Michael addition.

Palladium-catalyzed dominoHeck–aza-Michaelreactions for the synthesis of a series of C1-substituted tetrahydro-β-carbolines, tetrahydroisoquinolines and isoindolines are described. The domino process involves the initial intermolecular Heck reaction of an aryl bromide with an electron deficient alkene, followed by an intramolecular aza-Michael reaction to form the new N-heterocycle in high yield
