Cut and sew: A rhodium‐catalyzed regioselective carboacylation reaction of benzocyclobutenones was developed (see scheme). Directed by the pendant olefins, the C1C2 bond is selectively cleaved rather than the C1C8 bond. Subsequent alkene insertion leads to complex fused‐ring systems. This reaction provides facile access to natural‐product‐like polycyclic structures in a chemoselective and atom‐economic
