  Convergent stereospecific synthesis of C292 (or LL-Z1640-2), and hypothemycin. Part 1

  摘要：

  The stereospecific synthesis of the precursors required for the 14-membered ring formation either via an intramolecular Suzuki coupling or via an intermolecular Suzuki coupling followed by a macrolactonisation is herein reported. One-pot Suzuki couplings were here achieved with vinyldisiamylboranes which were generated in situ from the related chiral precursor. The present convergent approach of C292 (or LL-21640-2) and hypothemycin gives a flexible access to related macrolides. (C) 2002 Elsevier Science Ltd. All rights reserved.
