Historically, two approaches have been reported for achieving enantiomerically enriched compounds. The first approach is through asymmetric chemical transformations involving chiral pools, chiral auxiliaries, chiral reagents, and/or enantioselective catalysis/biocatalysis. 1 The second approach is through the preparation of the racemic mixture and the separation of enantiomers by means of chiral separation. 2 These two pathways, however, have their own disadvantages. While the former requires a suitable precursor—auxiliary, reagent, or catalyst—the latter is generally time consuming and yields only up to 50% of the desired enantiomer.
