In a cyclic process, fed with external chemical energy generated by the transformation of a compound with high chemical potential to carbon dioxide, the undesired enantiomer from a catalytic asymmetric reaction is continuously recycled to starting reagent. This minor enantiomer recycling is characterized by gradually increasing yields and product enantiomeric ratios. The requirements for maintaining a cyclic procedure are discussed; the necessity of a coupled exergonic process is demonstrated experimentally.
