Pig liver esterase (PLE)-mediated resolution of N-substituted 4-benzoyloxy-3-carbomethoxypiperidines: a convenient preparation of 4-hydroxy- and 4-benzoyloxy-3-carbomethoxypiperidines in enantiomerically pure form
ester groups, the latter being more easily hydrolyzed. The proposed methodology also represents a practical means for the procurement of N-substituted 4-hydroxy-3-carbomethoxypiperidines in enantiomericallypureform.
