Stereoselective synthesis of the H ring of gambierol was achieved from 2-deoxy-D-ribose by using the intramolecular reaction of allylstannane with aldehyde as a key step. Mollified Stille coupling was successfully applied for the construction of the triene side chain. (C) 1998 Elsevier Science Ltd. All rights reserved.
