“Formation of all-carbon quaternary centers by copper-catalysed asymmetric conjugate addition”
CHIMIA 2008, 62, 461-464.
This mini-review deals with a special, and challenging, aspect of the asymmetric conjugate addition: the formation of all-carbon quaternary centers by reaction with Michael acceptors bearing a polysubstituted unsaturation. Only copper catalysts allow this transformation, along with a careful choice of primary organometallics and chiral ligand. The resulting adducts are useful intermediates for the synthesis of more complex natural products.
