摘要
Tropone has been transformed into an optically pure tricyclic system that could serve as an advanced intermediate in the synthesis of ceroplasteric acid. The sequence features a stereoselective Ireland ester enolate Claisen rearrangement followed by an intramolecular nitrile oxide cycloaddition for assembly of an ABC-ring precursor of the target molecule. Efforts to homologate the seven-membered B ring to the requisite eight-membered system were unsuccessful.
