Rhodium-Catalyzed Multicomponent-Coupling Reactions Involving a Carborhodation−Cross-Coupling Sequence
摘要:
A rhodium-catalyzed multicomponent-coupling reaction has been developed that involves a cross-coupling with organohalides as part of the reaction sequence. Through several experiments toward mechanistic investigations, it has also been demonstrated that the reaction most likely proceeds via a carborhodation-oxidative addition-reductive elimination pathway, which clearly contrasts to the corresponding palladium-catalyzed processes.
A general and efficient method for the tertiary amide synthesis has been developed via copper-catalyzed aerobicoxidative amidation of tertiaryamines. Due to the use of O2 oxidant, various functional...
