Faktor-I, the chlorin which arises by aromatisation of the mono-C-methylated intermediate on the biosynthetic pathway to vitamin B12, has been synthesized in racemic form as its octamethylester by ring-closing the macrocycle photochemically.

Sirohydrochlorin is an isobacterichlorin isolated (a) as the metal-free prosthetic group of sulphite reductase and (b) as the aromatised form of the di-C-methylated intermediate on the biosynthetic pathway to vitaminB12; the synthesis is described of the natural enantiomer of sirohydrochlorin and also of its octamethyl ester using a mild photochemical route.
