The reaction of the diboroacetates of 1,4-diamino- and 1-amino-4-hydroxyanthraquinones with CH acids in an aprotic polar solvent in the presence of a base leads to the angular 5-amino- and 5-hydroxynaphtoindole-6,11-diones respectively.In the reaction of the diboroacetate of 2,3-dichloro-1,4-diaminoanthraquinone with dibenzoylmethane the main reaction product is the linear 4,11-diaminoanthrafuran-5,10-dione.
