摘要
7-substituted 3,4-diphenylpyrimido[4',5':4,5]thieno[2,3-c]pyridazines were synthesized starting from 5-amino-3,4-diphenylthieno[2,3-c]pyridazine-6-carbohydrazide (1). Reaction of carbohydrazide 1 with phthalic anhydride afforded 12,13-diphenyl-6H-pyridazino-[3",4":5',4']thieno[3',2':4,5]pyrimido-[2,1-a]phthalazine-5,6-dione, (6) which underwent further transformation to the related compounds.
