Activation of Pig Liver Esterase in Organic Media with Organic Polymers. Application to the Enantioselective Acylation of Racemic Functionalized Secondary Alcohols
the aldehyde and the acid through imine formation and neutralization, respectively, but replenish at least in part also the water consumed in the competing hydrolysis of the acyl donor. A recovery of PLE together with the polymer was achieved without major loss of activity through their immobilization on a water-saturated polyaramide membrane, which occurs spontaneously in organic solvents.
