Abstract

Controlling enantioselectivity in additions to oxocarbenium ions remains a challenge in asymmetric catalysis. By using a catalytically generated chiral organometallic intermediate, a copper acetylide, we have developed a novel approach for additions of carbon nucleophiles to cyclic oxocarbenium ions in high enantioselectivities and yields.
