Abstrakt: High yield syntheses of all four atropoisomers of the meso-tetrakis(o-catecholamidophenyl)porphyrin has been achieved; all four atropoisomers were isolated and characterised by NMR spectroscopy; for the methyl protected 2αβαβ and 2α4 atropoisomers obtained as water and chloroform solvates respectively, X-ray analysis was used to assign their structure.
