The dynamic kinetic resolution (DKR) has gained increasing attention because it is a simple method to obtain optically pure compounds from racemic substrates in quantitative yields. DKR is typically performed by a combination of kinetic resolution of racemates and in situ, continuous, and rapid interconversion between two enantiomers of the substrates, namely, racemization. We recently reported a new DKR method based on the combination of lipase-catalyzed kinetic resolution of racemic secondary alcohols and the V-MPS-catalyzed in situ racemization. In V-MPS, oxovanadium moieties were covalently bound to the inner surface of mesoporous silica (MPS) with a pore size of 2–4 nm. In this article, we introduce the background of why we used MPS, reaction characteristics of V-MPS, advantages of our DKR method, and its synthetic applications.
