The structure of tricyclodehydroisohumulone was investigated by 300 MHz 1H‐NMR and other spectroscopic methods. It is either 3‐(3‐methylbutanoyl)‐10‐(1‐methylethenyl)‐4,5‐dihydroxy‐9,9‐dimethyl‐tricyclo [6.3.0.01,5]undec‐3‐ene‐2,6‐dione or 3‐(3‐methylbutanoyl)‐9‐(1‐methylethenyl)‐4,5‐dihydroxy‐11,11‐dimethyl‐tricyclo[6.2.1.01,5]undec‐3‐ene‐2,6‐dione. Other criteria lead to a preference for the first structure.
