The unnatural bile pigment analog of bilirubin-IXα, 2,3,7,13,17,18-hexamethyl-(10H,21H,23H,24H)-bilin-1,19-dione-8,12-dicarboxylic acid (1), was synthesized as its diethyl ester by coupling 4,4′-dimethyl-3,3′-dicarboethoxydipyrrylmethane-5,5′-dialdehyde with 3,4-dimethylpyrrolin-2-one.
胆红素-IXα,2,3,7,13,17,18-六甲基-(10 H,21 H,23 H,24 H)-胆素-1,19-二酮-8,12-的非天然胆色素类似物通过将4,4'-二甲基-3,3'-二苯乙氧基二吡咯基甲烷-5,5'-二醛与3,4-二甲基吡咯啉-2-一偶合,合成二羧酸(1)作为其二乙酯。
