A Novel Synthesis of Cyclopenta[c]pyridazines and 1,8-Ethanophthalazinones: A New Ring System
Elassar, Abdel-Zaher Abdel Aziz
, p. 580 - 595 (2007/10/03)
Cyclopentylidene derivatives 1a,b readily couple with aryl diazonium salts to give the cyclopenta[c]pyridazine derivatives 3a-d. Compounds 3a,b reacted with arylidenemalononitrile or active methylene nitrile derivatives to give 1,8-ethanophthalazinone 6a-f, 13 and 15. Cyclopenta[c]pyridazines 3a,b reacted with ethyl acetoacetate or acetylacetone to afford the ethyl butanoate or pentanone derivatives 16a,b, respectively.
Studies on Cinnamonitriles: The Reaction of Cinnamonitriles with Cyclopentanone
Sofan, Mamdouh A.,El-Taweel, Fathy M.,Elagamey, Abdel Ghani A.,Elnagdi, Mohamed H.
, p. 935 - 936 (2007/10/02)
Cyclopentanone reacts with arylidenemalononitriles 1a-c to give dihydro-4,6-indenedicarbonitriles 5a-c.Similarly, the diethyl dihydro-4,6-indenedicarboxylate derivative 6 is formed when treating ethyl α-cyanocinnamate (1d) with cyclopentanone.Cyclopentab
