On treating xanthobilirubic acid methyl ester with bromine in methanol, a red bile pigment, which was assigned the hitherto unknown 16,24-dehydrobiladiene-ab constitution, is obtained in 20percent yield.In addition, the corresponding mesobiliverdin-XIIIα, mesobilirubin-XIIIα, 14-formyl-tripyrrinone, and two diastereomeric 15,16-dimethoxybiladienes-ab could be isolated from the reaction mixture.The mechanistic aspects of this reaction are discussed. - Keywords. 16,24-Dehydrobiladiene-ab; Biladiene-ab; Xanthobilirubic acid methyl ester; Mesobilirubin-XIIIα; Mesobiliverdin-XIIIα; 14-Formyl-tripyrrinone; 15,16-Dimethoxy-biladienes-ab.
