Abstract
An NMR study of 15‐epiclusianone, 1‐benzoyl‐6‐hydroxy‐14,14‐dimethyl‐3,5,15‐tri(3‐methyl‐2‐butenyl)‐bicyclo[3.3.1]non‐1‐ene‐4,6‐dione (1), a novel tetraisoprenylated benzophenone isolated from pericarp of fruits of Rheedia gardneriana, is described. In addition to conventional 1D NMR techniques, 2D shift‐correlated NMR experiments [1H × 1H‐COSY, 1H × 13C‐HMQC‐1J(C,H), 1H × 13C‐HMBC‐nJ(C,H) (n = 2 and 3) and 1H × 1H‐NOESY] were used for 1H and 13C chemical shift assignments of this natural product. The 1D 13C NMR spectrum of 1 in the solid state was also obtained. Copyright © 2001 John Wiley & Sons, Ltd.
