Cycloaddition of C,C-Disubstituted Ketonitrones with Acceptor Methylenecyclopropanes and Subsequent Rearrangement Cascade of 5-Spirocyclopropane-isoxazolidines

A new reaction cascade to give tricyclic cores of 2,4‐dihydro‐1H‐azeto[1,2‐a]quinolines (benzocarbacephems) and pyrrolo[1,2‐a]quinolines starting from acyclic N‐aryl ketonitrones and acceptor ring substituted methylenecyclopropanes has been reported. This reaction includes 1,3‐dipolar cycloaddition...
