Combinations of Crystallization and Racemization

In this book, we have prioritized separation techniques based on synthetic chemical steps over ones based on crystallizations. There are, however, two combinations of processes that deserve a brief further note, partly because of the spectacular results that are possible and partly because they have found usefulness in larger-scale preparative processes. In Chapter 5 was described the process of DKR, wherein a chemical synthetic transformation is used in conjunction with a chemical 

1) This concept was foreshadowed in Kagan s original 1974 paper Ref [48] as a chain of weakly asymmetric reactions.
