title: 1H and 13C NMR signal assignments of a novel Baeyer-Villiger originated diterpene lactone.
abstract: A highly rearranged novel dilactone was the single product isolated from Baeyer-Villiger oxidation of a norketone prepared from grandiflorenic acid, a natural kaurane diterpene. The complete 1H and 13C NMR assignment is presented for this novel compound that showed discrete in vitro antibacterial activity.
