Palladium/norbornene chemistry: an unexpected route to methanocarbazole derivatives via three Csp3–Csp2/Csp3–N/Csp2–N bond formations in a single synthetic sequence

Abstract

A Catellani reaction terminated by palladacycle amination leading to methanocarbazoles is reported. The outcome is the formation of three different Csp³–Csp²/Csp³–N/Csp²–N bonds through a Heck reaction/C–H activation/double amination cascade in one process.
