Herein, we report a nickel‐catalyzed intramolecular dual annulation reaction of alkyl nitrile‐containing 1,2,3‐benzotriazine‐4(3H)‐ones to synthesize polycyclic quinazolinones. This catalytic reaction can construct the core structure of polycyclic quinazolinone alkaloids; therefore, we also apply this reaction as the critical step to access fifteen relevant alkaloids to demonstrate efficacy.

The alkaloid deoxypeganine and some of its derivatives have been subjected to reduction with sodium tetrahydroborate and with the complex NaBH4. BF3. Et2O. It has been shown that the structures of the reduction products depend on the presence and positions of substituents in the benzene ring. The quantum-chemical calculations performed have confirmed the probable formation of reduced structures of the type of o-aminobenzylpyrrolidine and the type of a macrocyclic diamine.
