Abstract:A significant enhancement of the enantioselectivity (E value = 249) in the lipase-catalyzed resolution of a primary alcohol, racemic 5-(hydroxymethyl)-3-phenyl-2-isoxazoline (±)-1, was obtained by using the ‘low-temperature method’ (−60 °C) with porous ceramic-immobilized lipase (Amano PS-C II) and vinyl acetate in acetone.
