Article abstract of DOI:10.1246/cl.1993.279

5,10,15,20-Tetrakis(2-amino-6-methoxycarbonylphenyl)porphyrin was synthesized and three atropisomers in four were successfully separated.Different from the related mono-substituted tetraphenylporphyrins (2-amino- and 2-methoxycarbonylphenylporphyrins), the rotation of the bond between phenyl and porphyrin rings was totally prohibited under thermal isomerization.
