Synthetic studies toward potent cytotoxic agents amphidinolides: Synthesis of the C1C18 moiety of amphidinolides G, H and L
摘要:
Stereoselective synthesis of the (8S, 9S, 11R, 16S)-C-1-C-18 Segment 1 of amphidinolides G, H and L, bearing the unique trisubstituted "s-cis-1,3-diene" moiety (C-28(29)=C-13-C-14=C-15), has been achieved for the first time following a highly efficient convergent strategy.

The first synthesis of (+)-6'-hydroxyarenarol 3, the proposed biogenetic precursor to popolohuanone E (1), is described. An enantioselective route to key iodide intermediate 12 has been developed allowing the asymmetricsynthesis of the known cis-decalin 22. Conditions which allow the removal of the methyl ether protecting groups on the hydroxyarene leaving the exocyclic methylene moiety in tact have
