Cyclization of a pentapyrrane with two terminal β-linked pyrroles afforded a
dihydrosapphyrin isomer (1) with the pyrroles linked in a unique β, α–α, β mode, which was …

The aromatic nature of porphyrins is commonly attributed to the presence of an [18]
annulene substructure. However, this viewpoint has been disputed. Drawing on a range of …
