Total synthesis of (±)-ligudentatol via photoaddition-fragmentation-aromatic annulation sequence

Article abstract of DOI:10.1016/S0040-4039(97)21374-2

First synthesis of the naturally occurring compound (+)-ligudentatol is presented. It demonstrates the synthetic utility of the 'Photoaddition-Fragmentation-Aromatic Annulation' sequence, recently developed via the intramolecular photocycloaddition of dihydropyrones to alkenes.
