Resolution of 2-aryloxy-1-propanols via lipase-catalyzed enantioselective acylation in organic media
摘要:
2-Aryloxy-1-propanols, primary alcohols with an oxygyen 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 mid temperature, Using this enantioselective acylation procedure. enantiomeriocally pure (R)-2-(4-chlorophenoxy)-1-propanol was prepared on a grain scale.
