Resolution of racemic 4-hydroxy-2-cyclopentenone with immobilized penicillin G acylase
Kumaraguru, Thenkrishnan,Fadnavis, Nitin W.
, p. 775 - 779 (2012)
Enantiomerically pure 4-oxo-2-cyclopentenyl derivatives were prepared by kinetic resolution with penicillin G acylase (EC 3.5.1.11) immobilized on an epoxy activated polymer. The enzyme selectively hydrolyzes the phenylacetyl ester of the (S)-enantiomer t
