Abstract
Iridium-catalyzed tandem dehydrogenation of N-heterocycles and alcohols enables regio-selective C-H and N-H bond functionalizations of indolines to provide a diverse range of N- and C3-alkylated indolines/indoles. The practical applicability of this methodology was demonstrated by the preparative-scale synthesis and synthesis of a psychoactive drug, N,N-dimethyltryptamine.
