Diels-Alder in Heterocyclic Synthesis: A Novel Synthesis of Cycloalkanopyridazinimine,1,7-alkanothienopyridazines and 1,8-alkanophthalazines: New ring system
Transformation of the newly synthesized alkano[c]pyridazines and 1,7 propanothienopyridazines into 1,8-propanophthalazinones and 1,9-propanothiepinopyridazinones using [4+2] cycloaddition reaction with electron poor olefins and acetylenedicarboxylate derivatives, respectively is described.
