Title
Lipase-catalyzed enantioselective acylation of 3-benzyloxypropane-1,2-diol in supercritical carbon dioxide
Abstract

Lipase-catalyzed acylation of 3-benzyloxypropane-1,2-diol with vinyl acetate as acyl donor using different lipases [porcine pancreas lipase (PPL), Lipase AK “Amano”, Lipase PS “Amano”, and crude enzymes from Trichoderma reesei RUT-C30, Thermoascus thermophilus (NRRL5208), Talaromyces emersonii (NRLL3221)] was studied in supercritical carbon dioxide (scCO2). In the reactions catalyzed by different lipases different amounts of monoacetate and diacetate products along with minor amounts of cyclic acetals forming from the diol and acetaldehyde were obtained.Application of Lipase AK led to the highest conversion (84.7%) and the highest enantiomeric excess values (eemonoacetates = 38%, eediacetate = 85%). Effect of water content of scCO2 on the productivity and the enantiomer selectivity of the reactions with Lipase AK was also investigated.
