Total synthesis of bioactive drimane–epoxyquinol hybrid natural products: macrophorin A, 4′-oxomacrophorin A, and 1′-epi-craterellin A
摘要:
Total synthesis of novel hybrid natural products, merosesquiterpenoids macrophorin A, 4'-oxomacrophorin A, and l'-epi-craterellin A has been accomplished following a general strategy based on a sacrificial Diels-Alder-retroDiels-Alder approach to control regio- and stereoselectivity.

The synthesis of the marine natural products zonarone and isozonarone was achieved via (+)-albicanic acid, a sesquiterpene of the drimane type. Coupling of the appropiate drimane-synthon with lithiated hydroquinone ethers led to sesquiterpene arenes, which were further modified to the target molecules. Stereoselective epoxidation followed by regioselective opening of the oxirane ring yielded yahazunol. (C) 2002 Elsevier Science Ltd. All rights reserved.

The totalsynthesis of the naturally occurring sesquiterpene hydroquinones zonarol and isozonarol and the sesquiterpenequinones zonarone and isozonarone was achieved starting from β-ionone, which was transformed via (+)-albicanic acid to (+)-albicanal and (−)-drim-7-en-11-al. Coupling of the aldehydes with lithiated hydroquinone ethers and further modification of the coupling products led to the target
