Studies with model compounds have led to the development of effective methods for (a) linking the pyrrolic rings to the reduced rings present in the isobacteriochlorin system and (b) for introducing the carbon at C-5 required to complete the macrocycle. In the course of this work, many new pyrrolic systems have been prepared and characterised.
