    A variety of internally N-alkylated N-confused porphyrins were prepared in a stepwise manner through the protection of the reactive peripheral nitrogen atom. NH-Tautomerism in N-confused porphyrins was found to be regulated by N-alkylation, which enabled us to obtain discrete information on two important NH-tautomers of an N-confused porphyrin.
