Abstract

Using the recently developed route through di-t-butyl b-bilene-1,19-dicarboxylates, new syntheses of biliverdin-IXα dimethyl ester (1) and two related mono-vinyl-mono-ethyl isomers (2) and (3), are described. The two dihydro-derivatives of (1) are important in connection with biosynthetic studies of the origin of algal biliproteins. © 1984.
