Abstract
Using 3-methyl-1-dimethylamino-1-azabuta-1, 3-diene and 3 (tert-butyldimethylsilyl) oxy-1- dimethylamino-1-azabuta-1, 3-diene as 1-azadienes-and quinoline-5, 8-dione and carbostyrilquinone as dienophiles, several diazaanthraquinones have been obtained. Structure assignments were mainly based on IR spectroscopic data. The accessibility of N- oxidation products has been also investigated.
