Upon treatment of 9-methyl-10H-dipyrrin-1-ones with bromine in dichloromethane, red bile pigment derivatives were obtained in moderate yields. They were structurally assigned as 1,2-bis-dipyrrinon-9-yl-ethenes, which are examples of the hitherto unknown h-homo-verdins. In addition, the corresponding meso-biliverdins-XIII alpha could be isolated from the reaction mixture. The mechanistic aspects of the reaction are discussed.
