The acid hydrazides bearing furyl, pyrazolyl, and indolyl rings 2 condense with isatin to give the corresponding hydrazones 3. Ring closure of the latter in an HCl=AcOH mixture led to the construction of a new pyrrolinone ring 4. The hydrazides 2 condensed also with phthalic anhydride to give the corresponding pyridazinophthalazines 5.
