## Abstract Biliverdin dimethyl ester (**1b;** IXฮฑ) and its XIIIฮฑ isomer **2b** have been isolated on a preparative scale after esterification of an isomeric mixture obtained by oxidation of bilirubin. Both isomers readily form solid solutions. The substitution patterns and the predominant helical
