  Chemoenzymatic asymmetric synthesis of fluoxetine, atomoxetine, nisoxetine, and duloxetine

  摘要：

  The asymmetric synthesis of two well-known anti-depressant drugs, fluoxetine and duloxetine has been accomplished in a chemoenzymatic manner. The main highlight of the synthesis is the enantioselective cyanohydrin formation by a plant (R)-HNL (hydroxynitrile lyase). The enantiopure cyanohydrins are then synthetically manipulated into the above two drug molecules and two of their structural analogues, atomoxetine and nisoxetine. (C) 2013 Elsevier Ltd.

  [reaction: see text] The rhodium(I)-catalyzed methylenation of ketones using trimethylsilyldiazomethane proceeds to give the corresponding alkenes in good yields (60-97%). The use of an excess of 2-propanol and 1,4-dioxane as a solvent were instrumental to obtain the desired alkenes in high yields. Superior results were achieved with the rhodium(I)-catalyzed methylenation in comparison with the standard

• Fluorinated Porphyrin Tweezer:  A Powerful Reporter of Absolute Configuration for <i>erythro</i> and <i>threo</i> Diols, Amino Alcohols, and Diamines
  作者：Xiaoyong Li、Marina Tanasova、Chrysoula Vasileiou、Babak Borhan

  DOI：10.1021/ja0752639

  日期：2008.2.1

  working model suggests that the observed helicity of the porphyrin tweezer is dictated via steric differentiation experienced by the porphyrin ring bound to each chiral center. A variety of erythro and threo substrates were investigated to verify this chiroptical method. Their absolute configurations were unequivocally determined, and thus a general mnemonic is provided for the assignment of chirality
