Regioselective phenol-quinone addition of juglone (1a), 7-methyljuglone (1b), and stypandrone (1c) in pyridine yields the dimers 3,3-bijuglone (5a), mamegakinone (5c), and dianellinone (5e).In acetic acid mainly the cyclo trimers cyclo-trijuglone (12a), xylospyrin (12d), and trianellinone (12g) are obtained.
