Divergent reactions on racemic mixtures

Methods that furnish enantioenriched products are crucial in modern organic synthesis. An underutilized strategy to arrive at enantioenriched products is to perform divergent reactions on racemic mixtures, where each enantiomer of the starting material reacts with a single chiral reagent to furnish two separable, non-enantiomeric products that are enantioenriched. Stereodivergent, regiodivergent and structurally divergent reactions on racemic mixtures are discussed in this tutorial review.
