An asymmetric hydrogenation process of 3-substituted pyridine derivatives has been developed with the use of a Rh-TangPhos complex as the catalyst. The whole process consists of an efficient partial hydrogenation of nicotinate and a subsequent highly enantioselective, Rh-catalyzed, homogeneous hydrogenation. A series of chiral nipecotic acid derivatives have been synthesized. (© Wiley-VCH Verlag GmbH
使用 Rh-TangPhos 配合物作为催化剂开发了 3-取代吡啶衍生物的不对称氢化工艺。整个过程包括烟酸盐的有效部分氢化和随后的高度对映选择性、Rh 催化的均相氢化。已经合成了一系列手性尼泊松酸衍生物。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
