Abstract: Michael reactions of 4, 4-dimethoxycyclohexa-2, 5-dienone (2), readily available by electrochemical or chemical oxidation of p-methoxyphenol, were studied. Reaction of 2 with morpholine gave a mono-Michael adduct; methoxide gave a mixture of mono and bis adducts, and MeSH and PhSH gave only bis adducts. Reaction of 2 with Na2S gave good yields of a novel polycyclic compound, decahydro-3, 3, 8, 8-tetramethoxy-2, 7-epithio-l, 4- ...
