title: Tetra-N-confused cyclohexapyrrole: the unusual product formed by condensation of 3,3'-dipyrromethane with tripyrrin-aldehyde.
abstract: Novel tetra-N-confused cyclohexapyrrole is synthesized for the first time via condensation of tripyrrinone-aldehyde with bis(2,4-dimethylpyrrole-3-yl)methane in the presence of p-toluenesulfonic acid monohydrate. X-ray crystal analysis indicates that it adopts a nonplanar conformation with a conelike shape.
