  New chiral 2,2′-bipyridine diols as catalysts for enantioselective addition of diethylzinc to benzaldehyde

  摘要：

  New C-2-symmetric chiral 2,2'-bipyridine diols were prepared from readily available homochiral materials such as menthone and camphor. Their catalytic activities in the reaction of diethylzinc with benzaldehyde to give 1-phenyl-1-propanol were studied. In all cases, the yields were good and enantioselectivities up to 95% were observed. (C) 1999 Elsevier Science Ltd. All rights reserved.

• Practical iron-catalyzed dehalogenation of aryl halides
  作者：Waldemar Maximilian Czaplik、Sabine Grupe、Matthias Mayer、Axel Jacobi von Wangelin

  DOI：10.1039/c0cc01980a

  日期：——

  An operationally simple iron-catalyzed hydrodehalogenation of aryl halides has been developed with 1 mol% Fe(acac)3 and commercial t-BuMgCl as reductant. The mild reaction conditions (THF, 0 °C, 1.5 h) effect rapid chemoselective dehalogenation of (hetero)aryl halides (I, Br, Cl) and tolerate F, Cl, OR, SR, CN, CO2R, and vinyl groups.

  开发了一种操作简便的铁催化的芳基卤化物氢脱卤反应，使用1 mol%的Fe(acac)3和商业化的t-BuMgCl作为还原剂。温和的反应条件（THF溶剂，0°C，1.5小时）实现了(杂)芳基卤化物（碘、溴、氯）的快速化学选择性脱卤，并能耐受氟、氯、烷氧基、硫醚、氰基、羧酸酯和乙烯基等官能团。

  A series of new 1,1'-bi-2-naphthol (BINOL) derived ligands, 3-[6-(hydroxymethyl)pyridin-2-yl]-BINOLs or 3,3'-bis[6(hydroxymethyl)pyridin-2-yl]-BINOLs, bearing one or two chiral pyridinylmetlianols attached to a binaphthyl skeleton, have been synthesized using the Suzuki cross-coupling reaction. The resulting compounds have been used as ligands in the enantioselective addition of diethylzinc to aldehydes;
