Professor Karl Anker Jørgensen and his group have developed ethers which serve as excellent chiral organocatalysts in the direct asymmetric α-functionalization of aldehydes.
Professor Geoffrey Coates and co-workers at Cornell University have reported the preparation and use of catalysts composed of an oxophilic Lewis acid and a cobalt tetracarbonyl anion for the ring expansive carbonylation of epoxides to b-lactones and b-lactones to succinic anhydrides.
