Core assembly: The totalsynthesis of the myxobacterial metabolite rhizopodin, a potent actin‐binding anticancer agent, has been achieved. The modular synthesis utilizes a common C1–C22 monomeric unit to assemble the dimeric 38‐membered macrodiolide core, which was elaborated by a bidirectional boron‐mediated aldol reaction to install the characteristic side‐chains. The final global deprotection was

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.
