The well-known preference of the hydrolase enzymes to attack a substrate from si face rather than re face was studied in the system via molecular modeling of the two tetrahedral intermediates. These studies revealed that the complexes modeled on re face for both the isomers of the racemate were highly unfavorable. Furthermore, the unpropitious steric Scheme 12.
