Developing Processes for Crystallization-Induced Asymmetric Transformation

Crystallization-induced dynamic resolution (CIDR) is an adaptation of dynamic resolution, a process that can afford in principle a quantitative yield of chiral product from a racemic starting material through in situ resolution. Crystallization-induced asymmetric transformation (CIAT) includes CIDR and the preparation of diastereomers and olefins that are driven by crystallization. The history of CIAT and CIDR processes is reviewed, along with key observations made by researchers. Recommendations are made for identifying opportunities for and developing CIAT processes.
