Azanaphthoquinones and 1-(dimethylamino)-3-methyl-1-azabuta-1,3-diene (methacrolein N,N-dimethylhydrazone) underwent extremely facile cycloaddition to aza- and polyazaanthraquinones after elimination of dimethylamine from the initial 1:1 cycloadduct and its subsequent oxidation.Introduction of a basic side chain into the 8-position of the azaanthraquinone occurred readily with primary amines and the 8-(tosyloxy) derivative, but more complex substitution patterns resulted with 5,8-bis(tosyloxy) derivatives and primary amines.
