Enantioselective ?-vinylation of aldehydes via the synergistic combination of copper and amine catalysis.
Ontology highlight
ABSTRACT: The enantioselective ?-vinylation of aldehydes using vinyl iodonium triflate salts has been accomplished via the synergistic combination of copper and chiral amine catalysis. These mild catalytic conditions provide a direct route for the enantioselective construction of enolizable ?-formyl vinylic stereocenters without racemization or olefin transposition. These high-value coupling adducts are readily converted into a variety of useful olefin synthons.
