Abstract
Peracetylated â-cyclodextrin has been employed as a macrocyclic additive to enhance the enantiomeric ratio E and reaction rate in Pseudomonas cepacia lipase (PSL)-catalyzed enantioselective transesterification of 1-(2-furyl)ethanol in organic solvents. The beneficial action of the cyclodextrin used as a regulator of lipase was tentatively interpreted as increasing the conformational flexibility of the enzyme and undergoing host–guest complexation with the product, thereby preventing product inhibition and leading to an enhancement of the enantiomeric ratio E and the reaction rate. The effect of the organic solvent on the present cyclodextrin-mediated enzymatic transesterification has been studied.
