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
