Novel synthesis of some isatin hydrazones and pyridazinophthalazines

Abou-Elmagd, Wael S.I.,Hashem, Ahmed I.

, p. 1083 - 1091 (2013/03/28)

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.
