Optimization of the kineticresolution of 2-amino-4-phenyl-butane was achieved at 80 °C using CAL-B-catalyzed aminolysis of carboxylic acids and their ethyl esters. The reactions carried out with long chain esters and the corresponding acids as acyldonors proceeded with remarkably high enantioselectivity. The use of carboxylic acids as acylating agents led to a marked acceleration of the reaction

thermolabile enzyme and metal catalyst for racemization of amines in chemoenzymatic dynamic kinetic resolution, requiring high temperature of operation, is enabled by carrying out the reaction in modifiedSoxhlet extraction system. Initial insights into the scope and limitations of the developed reaction system are discussed.
