A series of enantiomerically pure ligands containing a combination of proline and DPEN groups have been prepared and employed in the asymmetrictransferhydrogenation of ketones. In the case of cyclic ketones, alcohols with ee values of up to 98 % were obtained.
一系列包含脯氨酸和 DPEN 基团组合的对映体纯配体已被制备并用于酮的不对称转移氢化。在环酮的情况下,获得了 ee 值高达 98% 的醇。

application of chiral, non‐racemic ReV–oxo complexes to the enantioselectivereduction of prochiral ketones is described. In addition to the enantioselectivereduction of prochiral ketones, we report the application of these complexes to 1) a tandem Meyer–Schuster rearrangement/reduction to access enantioenriched allylic alcohols and 2) the enantioselectivereduction of imines.
描述了手性非外消旋 Re V - oxo 配合物在前手性酮的对映选择性还原中的开发和应用。除了前手性酮的对映选择性还原外,我们还报告了这些复合物在以下方面的应用:1)串联 Meyer-Schuster 重排/还原以获取对映体富集的烯丙醇和 2)亚胺的对映选择性还原。
