Practical Considerations in Kinetic Resolution Reactions

This review provides a critical analysis of catalytic kinetic resolution reactions from a practical perspective, asking the question of when, if ever, is kinetic resolution the best option for the synthesis of an optically active target. A series of crucial conditions are identified, and it is postulated that if all of them are met, then indeed kinetic resolution can be highly practical. A variety of catalytic kinetic resolution processes are evaluated in the context of these criteria, with particular emphasis on catalyst availability, substrate scope, availability of the racemic substrate and of alternative methods for accessing enantiopure substrate or product, and key experimental considerations. It is found that several catalytic systems have been developed that offer almost unbeatable methods for the preparation of useful chiral building blocks.
