摘要

Dynamic kinetic resolution (DKR) has recently become not only an alternative to the traditional kinetic resolution, but also a new procedure for asymmetric synthesis. Enzymes are usually the tools to effect this methodology (DKR), although new techniques have emerged through the use of asymmetric transition metal catalysis. All of these methods need two supplementary steps: racemisation together with a consecutive asymmetric transformation. A breakthrough in this area appeared with the powerful combination of enzymatic resolution and transition metal-catalysed racemi- sation.
