Abstract
6,8-Dimethylpyrimido[4,5-c]pyridazine-5,7(6H,8H)-dione has been shown to react with some secondary amines in the presence of an oxidant to produce 6,8-dimethylpyrrolo[2′,3′;3,4]pyridazino[6,5-d]pyrimidine-7,9(6H,8H)-dione derivatives. The reaction represents a new method of pyrrole-ring annulation to an azine nucleus via a tandem SNH–SNH process.
