A Nove Asymmetric ent—Kauranoid Dimer from Isodon enanderianus

Further investigation on the aerial parts of Isodon enanderianus afforded a novel asymmetric ent-kauranoid dimer,enanderi-nanin J(1).The structure of the dimer was elucidated by means of spectroscopic methods (including 2D NMR tecniques ),Enanderinanin J was a dimer of xerophilusin A and probably formed by [4+2] cycloaddition.【A Nove Asymmetric ent—Kauranoid Dimer from Isodon enanderianus】完成机构:[1]StateKeyLaboratoryofPhytochemistryandPlantResourcesinWestChina,KunmingInstituteofBotany,CinaeseAcademyofSciencesKunming,Yunnan650204,China [2]StateKeyLaboratoryofPhytochemistryandPlantResourcesinWestChin
