  pH调节喹啉在水中的不对称转移加氢

  摘要：

  在缓冲水中，各种各样的喹啉衍生物在空气中以铑催化剂1和甲酸钠作为氢源进行不对称转移加氢，以提供具有重要对映选择性的重要合成1,2,3,4-四氢喹啉（参见方案； R = H，Me，F，Cl，Br，OMe； R'＝烷基，芳基）。

  The monodentate BINOL-derived phosphoramidite PipPhos is used as ligand for the iridium-catalyzed asymmetric hydrogenation of 2- and 2,6-substituted quinolines. If tri-ortho-tolylphosphine and/or chloride salts are used as additives enantioselectivities are strongly enhanced up to 89%. NMR indicates that no mixed complexes are formed upon addition of tri-ortho-tolylphosphine.

  单齿BINOL衍生的亚磷酰胺PipPhos用作铱催化的2-和2,6-取代喹啉的不对称氢化的配体。如果使用三邻甲苯基膦和/或氯化物盐作为添加剂，对映选择性将大大提高至89％。NMR表明添加三邻甲苯基膦后没有形成混合的配合物。

  borane adduct and its borenium ion. This borenium ion was used as a metal-free catalyst for hydrogenating various substituted quinoline N-heterocycles under ambient conditions. Furthermore, this method was utilized to synthesize two drug molecules: galipinine and angustureine. A detailed DFT study was performed to understand this metal-free catalytic hydrogenation.

  Cobalt oxide/cobalt-based nanopartides featuring a core shell structure and nitrogen-doped graphene layers on alumina are obtained by pyrolysis of Co(OAc)(2)/phenanthroline. The resulting core shell material (Co3O4 Co/NGr@alpha-Al2O3) was successfully applied in the catalytic hydrogenation of a variety of N-heteroarenes including quinolines, acridines, benzo[h], and 1,5-naphthyridine as well as unprotected indoles. The peculiar structure of the novel heterogeneous catalyst enables activation of molecular hydrogen at comparably low temperature. Both high activity and selectivity were achieved in these hydrogenation processes, to give important building blocks for bioactive compounds as well as the pharmaceutical industry.
