Abstract

Pentapyrrole analogs of bilirubin and biliverdin have been prepared along with corresponding analogs where two dipyrrinones are attached to p-xylyl and m-xylyl groups. As determined by spectroscopic analysis and molecular modelling, the “expanded” yellow bilirubin analogs are able to adopt intramolecularly hydrogen bonded conformations.
