Recycling in Asymmetric Catalysis [PDF]
Accounts of Chemical Research, 2016 Cyclic reaction networks consisting of an enantioselective product-forming step and a reverse reaction of the undesired enantiomer back to starting reactant are important for the generation of compounds with high enantiomeric purity. In order to avoid an equilibrium racemic state, a unidirectional cyclic process where product formation and regeneration
