A Mesoporous-Silica-Immobilized Oxovanadium Cocatalyst for the Lipase-Catalyzed Dynamic Kinetic Resolution of Racemic Alcohols

V for resolution: A new oxovanadium catalyst (V‐MPS; see scheme) immobilized in the pores of mesoporous silica has been developed. The combined use of V‐MPS and lipases achieved the dynamic kinetic resolution of a wide range of racemic alcohols (1 or 2) to produce optically active esters 3 in high c...

Zusammenfassung:V for resolution: A new oxovanadium catalyst (V‐MPS; see scheme) immobilized in the pores of mesoporous silica has been developed. The combined use of V‐MPS and lipases achieved the dynamic kinetic resolution of a wide range of racemic alcohols (1 or 2) to produce optically active esters 3 in high chemical and optical yields. The paired catalysts retained high catalytic activity when reused up to six times.
