  An efficient synthesis of pironetins employing a useful chiral building block,(1S,5S,6R)-5-hydroxybicyclo[4.1.0]heptan-2-one

  摘要：

  A convergent total synthesis of pironetin 1 and related compound 2 using a chiral building block, (1S,5S,6R)-5-hydroxybicyclo[4.1.0]heptan-2-one 5 is described. Both the dithiane 47 and the epoxide 32 with proper substituents were employed as coupling partners to construct the whole carbon skeleton 48, which was converted to (-)-pironetin 1 and (-)-2 in few steps. The usefulness of 5 for polyketide synthesis was demonstrated. (C) 1999 Elsevier Science Ltd. All rights reserved.
