The synthesis of the compound that has been proposed to be the naturalproductsclerophytinF has been completed from a known vinylogous carbonate. The synthetic strategy relied upon rearrangement of a catalytically generated ylide-like intermediate to produce an oxabicyclo[6.2.1]-5-undecen-9-one and an intermolecular Diels–Alder reaction to construct the complete tricyclic core found in the natural

natural product sclerophytin F has been completed along with the syntheses of three diastereomers. Comparison of the NMR spectroscopic data for all four compounds to the data reported for the natural product reveals that sclerophytin F is not the 3S diastereomer of sclerophytin A as proposed by Friedrich and Paquette. Re‐analysis of the NMR spectroscopic data for known sclerophytin natural products and
