Multicomponent Coupling

A reductive coupling of two different carbonyls via a polar two-electron reaction mechanism was developed and the stereochemical outcome of this multicomponent process is precisely controlled by a chiral triaminoiminophosphorane.

Multicomponent Coupling

Multicomponent coupling reactions provide a method to combine several substrates in a single reaction. When coupled with transition-metal catalysis, these reactions can be used to both activate and control the assembly of multiple simple building blocks directly into useful products. This account will describe our work in this area, with a focus on the use of palladium catalysis as a tool to couple imines and CO with other substrates into a range of heterocyclic derivatives in one-step reactions.

The combination of photoredox and transition metal catalysis, which is termed metallaphotoredox catalysis, is a powerful platform for building complex molecules under mild conditions. In particular, metallaphotoredox-catalyzed multicomponent coupling reactions,...
