✦ Synopsis
Syntheses of Bile Pigments, XII. Synthesis of E,Z,Z‐Configurated Biliverdins from 5(1__H__)‐Pyrromethenones of the Same Configuration
(Z,Z,Z)‐ and (E,Z,Z)‐mesobiliverdin IIIα dimethyl esters 4 are obtained by acid‐catalyzed condensation of methyl 5′‐(tert‐butoxycarbonyl)isoneoxanthobilirubinate with methyl (Z)‐ and (E)‐5′‐formylisoneoxanthobilirubinate, respectively.
