A propargylic alcohol, enriched in the (R)-enantiomer, has the formula
1
wherein R is C
1-4
alkoxy, halogen, or C
1-4
alkyl optionally substituted by OH or halogen. This is prepared by the steps of:
(a) enantioselective (R)-esterification of the racemic alcohol using any acyl donor and a first enzyme;
(b) removal of the untreated (S)-alcohol; and
(c) enantioselective hydrolysis of the (R)-ester, using a second enzyme.
一种富含(R)-对映体的丙炔基醇,其化学式为1,其中R为C1-4烷氧基,卤素或C1-4烷基,可选择性地被OH或卤素取代。该方法通过以下步骤制备:(a)使用任何酰基供体和第一酶进行对映选择性的(R)-酯化反应;(b)去除未处理的(S)-醇;以及(c)使用第二酶进行对映选择性的(R)-酯水解反应。
