  名称：

  Optically pure 1,3-diols from (2R,4R)- and (2S,4S)-1,2:4,5-diepoxypentane

  摘要：

  Optically pure (> 97% ee) (2R,4R)-1,2:4,5-diepoxypentane (1) and its enantiomer can be prepared in three steps from 2,4-pentanedione without the need for chromatographic purification. Diepoxide 1 is an efficient precursor to a wide variety of optically pure syn and anti 1,3-diols. Reaction with excess nucleophile gives symmetric[GRAPHICS]anti 1,3-diols in good yield. Reaction with a slight excess of alkyllithium under Ganem's conditions gives the monoepoxides 5 in good yield. Addition of a second nucleophile to monoepoxide 5 gives asymmetric anti 1,3-diols. Mitsunobu inversion of monoepoxide 5 followed by addition of a second nucleophile gives syn 1,3-diols. Optically pure syn and anti 1,3-diols are available from diepoxide 1 in one to three steps and good overall yield.

  A concise and practical enantioselective synthesis of (+)-strictifolione has been achieved in high diastereomeric excess using Jacobsen's hydrolytic kinetic resolution, proline-catalyzed sequential α-aminoxylation and Horner-Wadsworth-Emmons olefination of aldehyde and cross olefin/ring-closing metathesis as the key steps.

  使用 Jacobsen 的水解动力学拆分、脯氨酸催化的顺序 α-氨氧基化和 Horner-Wadsworth-Emmons 醛的烯烃化和交叉烯烃/闭环复分解，以高非对映异构体过量实现了 (+)-strictifolione 的简洁实用的对映选择性合成关键步骤。
