Redox-neutral ?,?-difunctionalization of cyclic amines.


ABSTRACT: In contrast to the continuously growing number of methods that allow for the efficient ?-functionalization of amines, few strategies exist that enable the direct functionalization of amines in the ?-position. A general redox-neutral strategy is outlined for amine ?-functionalization and ?,?-difunctionalization that utilizes enamines generated in?situ. This concept is demonstrated in the context of preparing polycyclic N,O-acetals from simple 1-(aminomethyl)-?-naphthols and 2-(aminomethyl)-phenols.
