A novel heterocyclic system of 4,10-dihydro-3H-pyridazino[1,6-b]isoquinolin-10-one has been synthesized via acid-catalyzed recyclization of hydrazides of 2-carboxyphenyldifurylmethanes as well as by alternative synthesis by interaction of the corresponding isocoumarine ketones with hydrazine hydrate.
