N-confused Pyriporphyrin

N-Confusion of a pyridine ring in pyriporphyrin done by R. Myśliborski gave 6,11,16,21-Tetraaryl-3-aza-m-benziporphyrin a.k.a. N-confused Pyriporphyrin. Also 24-thia analogue was obtained and their properties an reactivity was investigated producing, among others, 6-hydroxy-3-aza-m-benziphlorin and iron complexes.
