Synthesis of 5,15-Diaryl-Substituted Porphyrins by Aminomethylation of Bis(4-ethyl-3-methyl-2-pyrryl)phenylmethanes

The synthesis of unsymmetrically diarylsubstituted porphyrins 11a-g (yields 5-19 percent) is described.Aminomethylation of dipyrromethane 6a with Mannich reagent 9 in acetonitrile leads to the intermediate 10, which is directly converted into the porphyri
