  Stereocontrolled synthesis of hydroxyethylamine isosteres via chiral sulfoxide chemistry

  摘要：

  A novel synthesis of enantiopure hydroxyethylamine isosteres has been developed. Reaction of lithiated beta-sulfinyl-ethylamines 3 with N-Cbz-irnines generated in situ from alpha-amino-sulfones 4 afforded in good to excellent yields and moderate stereocontrol the 2-sulfinyl-1,3-diamines 2. The latter were submitted to the nonoxidative Pummerer reaction (NOPR) in CH2Cl2, that produced the target compounds 1 in very good yields with inversion Of Configuration. In some cases, the use of acetonitrile as solvent resulted in a double-inversion pathway, leading for example to the oxazolidinone 5. The total synthesis of an epimer of Saquinavir has been achieved by this method. (C) 2004 Elsevier Ltd. All rights reserved.
