[reaction: see text]. Total syntheses of deoxyvasicinone (1), mackinazolinone (2), and 8-hydroxydeoxyvasicinone (3) via novel microwave-assisted domino reactions, as well as a novel three-component one-pot total synthesis of isaindigotone (5) promoted by microwave irradiation, are reported. The efficientreaction process enabled us to rapidly access related natural product derivatives and to identify

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.
