Remarkable Enhancement of Lipase Catalytic Activity: Combined Effects of Acyl Donor and Thiacrown Ether Additive during Trans-esterification of 5-Phenyl-1-penten-3-ol

Abstract
The Pseudomonas cepacia lipase-catalyzed trans-esterification of 5-phenyl-1-penten-3-ol was drastically accelerated by 5 mol% of a thiacrown ether additive. The reaction profile was strongly dependent on the nature of the vinyl esters as the acyl donor; the highest acceleration rate was recorded with vinyl chloroacetate, while the highest enantioselectivity was obtained using vinyl acetate.
