A round at the Oval: The antiangiogenic activity of the natural product ovalicin has sparked significant interest. A highly efficient enantio- and diastereoselective total synthesis of ovalicin proved successful in which the key step involved an endo selective Diels–Alder reaction (see scheme, PG=protecting group).
