Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Tetrahedron called Tetraoxa[24]porphyrinogen(4.0.4.0)/tetraoxa[22]porphyrin(4.0.4.0) dication. A further isomer of the aromatic 22π-tetraoxaporphyrins, Author is Maerkl, Gottfried; Hafner, Markus; Kreitmeier, Peter; Burgmeister, Thomas; Kastner, Fritz; Porsch, Michael; Daub, Joerg, which mentions a compound: 2689-65-8, SMILESS is IC1=CC=C(O1)C=O, Molecular C5H3IO2, Reference of 5-Iodo-2-furaldehyde.
While the antiarom. tetraoxa[24]porphyrinogen(2.2.2.2) (trans,cis,trans,cis) and the corresponding aromatic dication have been published recently, the synthesis of the title compounds is described for the first time. Besides the cis,trans,cis,trans-tetraoxa[24]porphyrinogen(4.0.4.0) (I) the isomeric porphyrinogens (trans,cis,cis,trans) and (all-trans in the cisoid conformation) could be isolated. I dication is an aromatic 22π-system which exists only in the cis,trans,cis,trans-configuration. I dication can be reduced with tetrakis-N,N-dimethylaminoethene to give pure I. The electrochem. of the system I/I2+ and AM1 calculations are described.
