A new, highly fluorescent (Phi(F) > or = 0.8) chromophore has been synthesized in one step from dipyrrinones by reaction with N,N-carbonyldiimidazole to form the 3H,5H-dipyrrolo[1,2-c:2',1'-f]pyrimidine-3,5-dione nucleus.
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.
