up of this KR process permitting a further rise in the catalytic efficiency. Finally, the dynamic kinetic resolution of benzoin (DKR) was carried out by the combination of the immobilized lipase and a ruthenium catalyst (Shvo’scatalyst) in 2-MeTHF, reaching conversions up to 90%, maintaining its excellent enantioselectivity during six catalytic cycles.

chemoenzymatic Dynamic Kinetic Resolution (DKR) of unsymmetrical benzoins (Ar1≠Ar2) has been carried out, by using Pseudomonas stutzeri lipase stereorecognition pattern. After studying this lipase behaviour, a high preference towards acylation of those benzoins containing substituents in the phenyl ring rather than in the benzoyl moiety was observed. This fact allowed the development of the DKR process of this
