Abstract

A synergistic combination of copper and chiral amine catalysis enables an enantioselective α-alkenylation of aldehydes using boronic acids. The merger of two highly utilized and robust catalytic systems has allowed for the development of a mild and operationally trivial protocol for the direct formation of α-formyl olefins employing common building blocks for organic synthesis.
