A propargylic alcohol, enriched in the (R)-enantiomer, has formula (I) wherein R is C1-4 alkoxy, halogen, or C1-4 alkyl optionally substituted by OH or halogen. This may be prepared by the steps of: (a) enantioselective (R)-esterification of the racemic alcohol using an acyl donor and a first enzyme; (b) removal of the unreacted (S)-alcohol; and (c) enantioselective hydrolysis of the (R)-ester, using a second enzyme. The alcohol can be converted to a prostaglandin by known means.
一种富含(R)-对映体的丙炔基醇,化学式为(I),其中R为C1-4烷氧基,卤素或C1-4烷基,可选地被OH或卤素取代。该醇可以通过以下步骤制备:(a)使用酰基供体和第一酶进行对映选择性的(R)-酯化反应;(b)去除未反应的(S)-醇;和(c)使用第二酶进行对映选择性的(R)-酯水解。该醇可以通过已知方法转化为前列腺素。
