Regioselective Synthesis of the Bridged Tricyclic Core of Garcinia Natural Products via Intramolecular Aryl Acrylate Cycloadditions
摘要:
[GRAPHICS]Two different routes to the tricyclic core of Garcinia-derived natural products are described. The first approach is based on a tandem Claisen/Diels-Alder rearrangement and delivers the desired lactone 14. The second approach, employing a Wessely oxidation/Diels-Alder protocol, leads to the same caged heterocycle, albeit with modified constitution.
