Continuous-flow stereoselective reduction of prochiral ketones in a whole cell bioreactor with natural deep eutectic solvents

Immobilized whole cells of Rhodotorula rubra MIM147 were used in a packed bed flow reactor for the enantioselective reduction of β-ketonitriles and for the obtainment of a key building block for the synthesis of the antidepressant drug duloxetine.
