• Stereoselective oxidation and reduction by immobilized Geotrichum candidum in an organic solvent
  作者：Kaoru Nakamura、Yuko Inoue、Tomoko Matsuda、Ibuki Misawa

  DOI：10.1039/a900936a

  日期：——

  Cells of the fungus, Geotrichum candidum, were immobilized on a water-absorbing polymer and used for stereoselective oxidation and reduction in an organic solvent using cyclohexanone, cyclopentanol or alkan-2-ols as additive. Enantiomerically pure (R)-1-arylethanols were obtained by the stereoselective oxidation of racemic 1-arylethanols, whereas enantiomerically pure (S)-1-arylethanols were obtained by the reduction of the corresponding ketones, in contrast to reduction in water by the free cells in which (R)- or (S)-1-arylethanols were produced in low ee.The reaction mechanism was investigated by measuring the partition of the substrates and products between the organic phase and aqueous phase in the polymer around which the cells were immobilized. Deuterated compounds were used to determine the role of the additives.

  将真菌地霉菌（Geotrichum candidum）的细胞固定在水吸收性聚合物上，并用于在有机溶剂中以环己酮、环戊醇或烷-2-醇作为添加剂进行立体选择性氧化和还原反应。通过立体选择性氧化外消旋1-芳基乙醇，获得了对映体纯的（R）-1-芳基乙醇，而通过对相应的酮进行还原，获得了对映体纯的（S）-1-芳基乙醇，这与自由细胞在水中的还原反应不同，后者仅产生低ee值的（R）-或（S）-1-芳基乙醇。通过测量细胞固定在聚合物周围的有机相和水分相中底物和产物的分布，研究了反应机制。使用氘代化合物来确定添加剂的作用。

  and iridium complexes of chiral NHC–phenolimine and NHC–amine ligands have been prepared and studied for asymmetric transfer hydrogenation. X-ray and NMR spectroscopy show that for NHC–phenolimine complexes abstraction of chloride results in a change in ligand coordination from NHC only to chelating NHC–imine. Complexes of NHC–amines are inactive for transfer hydrogenation, whereas complexes of NHC–phenolimines

  High throughput screening enabled the development of a Cu-based catalyst system for the asymmetric hydrogenation of prochiral aryl and heteroaryl ketones that operates at H2 pressures as low as 5 bar. A ligand combination of (R,S)-N-Me-3,5-xylyl-BoPhoz and tris(3,5-xylyl)phosphine provided benzylic alcohols in good yields and enantioselectivities. The electronic and steric characteristics of the ancillary

  Coordination with RuCl2(PPh3)dppb gave ruthenium(II) N-heterocyclic complexes 4b–d. The structure of complex 4b was fully illuminated by X-ray crystallography. The steric environment of these chiral ruthenium complexes 4b–d was evaluated in asymmetric transfer hydrogenation (ATH) of prochiral ketones in the presence of NaOiPr by using 2-propanol as the hydrogen source and solvent. The resultant catalytic
