Rhodium(<scp>iii</scp>)-catalyzed [3 + 3] annulation reactions of <i>N</i>-nitrosoanilines and cyclopropenones: an approach to functionalized 4-quinolones

Abstract

We report Rh(<sc>iii</sc>)-catalyzed [3 + 3] annulation reactions for the preparation of functionalized 4-quinolones from available <italic>N</italic>-nitrosoanilines and cyclopropenones.
