Oxidative Coupling of Enolates

Oxidative Coupling of Enolates

  • General Characteristics

Enolate species undergo dimerization under appropriately chosen oxidative conditions. Homo-coupling usually predominates, but there are successful examples of controlled hetero-coupling using carefully designed substrates.

  • Examples

In 2007, MacMillan reported the remarkable catalytic enantioselective version of enolate coupling, the reactivity of which has been explained by SOMO (singly occupied molecular orbital)-activation mechanism.[1]
