Biomimetic Synthesis toward the Transtaganolides/Basiliolides
摘要:
A concise biomimetic approach toward transtaganolides C and D involving an Ireland-Claisen rearrangement/intramolecular Diels-Alder reaction sequence suggesting the involvement of pericyclic reactions in the biosynthesis of these biologically active plant metabolites is presented. A final coupling reaction establishes the carbon framework of the transtaganolides.

The totalsyntheses of basiliolideC and previously unreported epi-basiliolide C are achieved by an Ireland–Claisen/Diels–Alder cascade. The development of a palladium catalyzed cross-coupling of methoxy alkynyl zinc reagents allows for the protecting-group-free syntheses of transtaganolidesC and D. Syntheses of transtaganolidesC and D are accomplished in a single operation to generate three rings
