In order to obtain a useful model system for the sedimentary tetrahydrobenzoporphyrins the title compound (X) is synthesized via an efficient approach, which is a practical alternative for the synthesis of such substances. Mono-labeling of (X) is achieved in an identical way using only (I) or (IX) i
Porphyrins with steric hindrance at the periphery are known to exhibit severely non-planar macrocycle conformations. Among other dodecasubstituted porphyrins, the title compound has been studied widely and shows a typical saddle-distorted macrocycle. The specific conformation of the porphyrin leads
