An unsymmetrically substituted 5,15‐diarylporphyrin 1 , with p ‐dimethylamino and p ‐carbomethoxy substituents, was synthesized via a MacDonald condensation of aryldipyrromethane precursors 6 and 12 , which were prepared in good yield by three or four step procedures starting from ethyl 3,4‐dimethyl‐1 H ‐pyrrole‐2‐carboxylate ( 2 ).
