Abstract
Penicillinacylase from E. coli, immoblized on Eupergit C beads catalyzes the hydrolysis in water/CH3CN 10: 1, at pH 7.5 and 23° C, of a set of O-phenylacetate esters of primary carbinols. The highest enantioselectivity is observed in the case of the 2, 2-dimethyl-1, 3- dioxolane-4-methanols structurally related to the penicillin (1) framework. Minor modifications of this basic structure are not altering the acceptability by the enzyme, but ...
