and photon correlation spectroscopy. It retains the activity of native PLE in the enantioselective hydrolysis of prochiral diesters 2, 4, 6 and 8 to the monoesters 3, 5, 7 and 9, respectively, in water. MPEG-PLE is soluble and active in organic solvents. The MPEG-PLE catalyzed acylation of prochiral diols 10 and 11 with vinyl acetate in toluene leads to monoacetates ent-5 and 9, respectively.
