Synthesis of Cinnolin-3(2H)-one Derivatives from Rh-Catalyzed Reaction of Azobenzenes with Diazotized Meldrum's Acid.
A synthetic method of a wide range of cinnolin-3(2H)-one derivatives is developed from the reaction of symmetrical as well as unsymmetrical azobenzenes with diazotized Meldrum's acid via Rh-catalyzed C-H alkylation followed by cyclization.
