The configurations of some isoxazolidinium salts have been determined by nuclear Overhauser effect difference spectroscopy (NOEDS). The stereochemical findings give a good explanation of the different reactivities experienced in the five-membered ring-opening process as a function of the steric requ
In addition to the previously reported bakkenolide-A, structure 11, and bakkenolide -B, 1,2,3 two new sesquiterpenoids, bakkenolides-C and -D, have been isolated from the bud of Petasites japonicus subsp. giganteus Kitam. The structures of the last three compounds are discussed in this communication
