Notes:
When kinetic resolution is applied for the production of enantiomerically pure compounds, process options may be used which involve more than one chiral substrate and one chiral product, such as sequential or parallel enzymatic kinetic resolutions or hydrolysis of diastereomers. Although the relation between the yields (y) of the chiral compounds is straightforward in these cases, the relation between their enantiomeric excess (ee) values is not. Combining mass balances into a so-called chiral balance (Σ y · eeR = 0) provides the relation between enantiomeric excess values in a useful manner. This chiral balance easily shows which nonmeasured enantiomeric excess values and yields can be calculated from measured values. The chiral balance is only valid when configurations at chiral centers are conserved. © 1995 John Wiley & Sons, Inc.
