2-Aryloxy-1-propanols, primary alcohols with an oxygen atom at the stereocenter, were resolved with good to high enantioselectivity by acylation with vinyl butanoate mediated by Pseudomonas sp. lipase in di-iso-propyl ether. Potential factors affecting the enantioselectivity of the enzymatic acylation were examined: solvents, acyl donors and temperature. Using this enantioselective acylation procedure, enantiomerically pure (R)-2- ...
