Abstract
Further investigation on the aerial parts of Isodon enanderianus afforded a novel asymmetric ent‐kauranoid dimer, enanderinanin J (1). The structure of the dimer was elucidated by means of spectroscopic methods (including 2D NMR techniques). Enanderinanin J was a dimer of xerophilusin A and probably formed by [4 + 2] cycloaddition.Keywords
