Cycloadditions of 1-(dimethylamino)-4-methyl-1-azabuta-1,3-diene to naphtoquinones afford after elimination of dimethylamine the 1,4-dihydro aza-anthraquinones . A high regioselectivity is observed with juglone and methyljuglone. Aromatization of compounds leads to the corresponding aza-anthraquinones .
