Treatment of protoporphyrin IX dimethyl ester (12) with benzoyl peroxideaffords a mixyure of the four isomeric meso-benzoiloxy derivaties (13) These have been separated by h.p.l.c. and distinguished from each other by hydrolysis to the corresponding oxophlorins (oxyporphyrins),insertionof iron to form the oxyhaems (3),and oxidation by molecular oxygen to the corresponding biliverdins (7).

Anaerobic irradiation of bilirubin in the region of the main absorption band produces the diastereomers of (Z,E)- and (E,Z)-configurations with high quantum yield.The structure of these "photobilirubins" is proven by a chemical correlation with the corresponding diastereomers of biliverdindimethylester characterised before.Their 1H-NMR spectroscopic features have been recorded and are discussed. - Keywords: (Z,Z)-, (Z,E)- and (E,Z)-Bilirubin; Photobilirubin; Neonatal jaundice; Phototherapy
