Abstract

A two-step protocol based on tandem Wessely oxidation/intramolecular Diels-Alder reaction to provide general access to the 3-prenyl-4-oxa-tricyclo[4.3.1.03,7]dec-8-en-2-one core present in the caged Garcinia xanthonoids is demonstrated. These readily accessible tricyclic scaffolds also provide ready entry into a variety of substituted λ -lactones through a photochemical 1,3-acyl shift and decarbonylation.
