The synthesis of four regioisomeric azaanthraquinones (4a, b and 5a, b) was achieved in a regioselective manner by the Diels-Alder reaction of 4- oxygenated 6-bromo- and 7-bromoquinolinequinones (11 and 15) with 1-methoxy- 3-trimethylsilyloxy-1,3-butadien
A synthesis of 1-azaanthraquinones via Diels-Alder reaction of 4- hydroxy- and 4-methoxy-2-phenylquinolinequinones with 3-trimethylsilyloxy- 1,3-butadienes: Observation of inverse regioselectivity
