  A Synthetic Approach to 3-Hydroxy 4-Substituted Carboxylic Acids based on the Stereoselective Reduction of 1-Trimethylsilyl-1-alkyn-3-ones

  摘要：

  The oxazaborolidine-mediated reduction of chiral, 4-substituted 1-trimethylsilyl-1-alkyn-3-ones followed by hydroboration affords syn or anti 3-hydroxy 4-substituted carboxylic acids, common substructures of a number of biologically active macrolides, peptides and depsipeptides, with high control on the new C(3) stereocenter. This strategy has been applied to the synthesis of (3S,4S)-3-hydroxy-4-methylheptanoic acid and of N-Boc-statine, constituents of permentin A and pepstatin, respectively.

  A flexible, efficient route to chiral 3-hydroxy-4-methyl- and 3-hydroxy-4-methoxyalkanoic acids, with high control of the C(3) configuration, has been disclosed, which is based on the borane-mediated reduction of 1-trimethylsilyl-1-alkyn-3-ones (6) in the presence of oxazaborolidine 7 followed by hydroboration of the resulting propargylic alcohols 4 and 5. This strategy has been applied to the synthesis of the Octalactin A ring. (C) 1998 Elsevier Science Ltd. All rights reserved.
