Reactions of aliphatic 2,2,3,3-tetracyanocyclopropyl ketones with aqueous ammonia afforded 4-alkyl- 4-amino-2-oxo-3-azabicyclo[3.1.0]hexane-1,6,6-tricarbonitriles with conservation of the three-membered ring. Reactions of the same compounds with primary amines were accompanied by opening of the cyclopropane ring, and they led to the formation of 5-amino-6,6a-dimethyl-2-oxo-1,2,6,6a-tetrahydropyrrolo[2,3-b]-pyrrole-3,4-dicarbonitriles as a result of successive heterocyclizations.
