"Haem d₁: Stereoselective synthesis of the reduced form of its parent macrocycle using the original coupling strategy"
J. Chem. Soc., Perkin Trans. 1,1997, 2099-2109. Full Text

A substituted isobacteriochlorin, which corresponds structurally to the reduced metal-free macrocycle of haem d1, has been synthesised by a stereoselective route in which the final step is a photochemical 18-pi-electron antarafacial cyclisation of an open-chain precursor.
