Retro: Cyclo[8]isoindole, which has a saddle-shaped geometry (see picture, 2), was synthesized by oxidative coupling of a bicyclo[2.2.2]octadiene(BCOD)- fused 2,2′-bipyrrole followed by a retro-Diels-Alder reaction of BCOD-fused cyclo[8]pyrrole (1). Key trends in the optical spectra of ring-annelated cyclo[8]pyrroles are identified based on magnetic circular dichroism spectra and theorectical calculations.
