Polycyclic Pyridazines. II. Synthesis of Pyrazolopyridopyridazine Derivatives from Dimethyl Pyrazolopyridazine-5,6-dicarboxylates as the Key Intermediates

The synthesis of the novel pyrazolopyridopyridazine ring system and some of its derivatives has been accomplished such as 4-amino-1-phenyl-5,8-dioxo-, 4-amino-5,8-dioxo-, 1-phenyl-5,8-dioxo-, 5,8-dioxo-, 5,8-dichloro-1-phenyl-, 5-ethoxy-1-phenyl- and 8-ethoxy-1-phenylpyrazolopyridopyridazines.
