Abstract

In order to obtain optically active fluorinated propargyl alcohols, a lipase-catalyzed kinetic resolution has been carried out. The effect of lipase types, organic solvents, reaction temperature, and acyl donors was examined in the lipase-catalyzed transesterification of 1,1,1-trifluoro-4-phenyl-3-butyn-2-ol. Various enantiomerically pure fluorinated propargyl alcohols have been successfully prepared in good enantiomeric excess (>84%) by Novozym 435-catalyzed transesterification with vinyl butanoate at 60 °C in n-hexane. In some cases, the enantiomeric purities were excellent (>99% ee).
