专利号:US-4921798-A 优先权日:1989-09-25 标题 :Synthesis of (aryl or arylalkyl)-3-hydroxy propionic acids and aryl alkanediols having high optical purity 发明人:BOAZ NEIL W 权利人:EASTMAN KODAK CO 摘要:R- and S-1-Phenyl-1,3-propanediol, each of high optical purity, were prepared by a chemoenzymatic sequence starting with ethyl benzoylacetate. The first step was a catalytic hydrogenation of the β-ketoester conducted at room temperature. The enzymatic hydrolysis of the resulting hydroxyester proceeded in a facile manner using a commercial preparation of the lipase from Pseudomonas fluorescens. The enzymatic hydrolysis proceeded at a moderate rate (350 mg lipase/0.10 mol of racemic ester required a 20-hour reaction time with an enantiomeric rate ratio (E value) of 36). The hydrolysis was run to 45-50% conversion to afford isolated S-3-phenyl-3-hydroxypropionic acid of 85-90% ee after separation from the residual ester (aqueous base extraction). The optical purity of the hydroxy acid was determined by conversion to the methyl ester (CH 3 I, KHCO 3 , acetone), and derivatization with S-MTPA-Cl, and 1 H NMR analysis. A single recrystallization of the isolated acid afforded optically pure (>98% ee) S-3-phenyl-3-hydroxypropionic acid in an overall 36% yield from the racemic ester. The acid was reduced with borane in THF to afford optically purs S-diol in 97% yield after crystallization. The overall sequence proceeded in 34% total yield from racemic ester with an additional 45-55% recovered as the antipodal ester. This antipodal ester is obtained in 85-95% ee, and the corresponding hydroxy-acid was readily obtained (NaOH), CH 3 OH/H 2 O) and recrystallized to optical purity. Reduction then afforded R-1-phenyl-1,3-propanediol in 30% to overall yield from racemic ester.
