  13C-labeled bilirubin: synthesis of 31(32),171(172)-di-[13C]-mesobilirubin-XIIIα

  摘要：

  The title compound, labeled with C-13 in the ethyl groups was synthesized from (KCN)-C-13 and low-molecular-weight components. The synthetic relay compound was 3(1)(3(2))[C-13]-xanthobilirubinic acid methyl ester in a synthetic route that leads to a label in the ethyl beta-substituent of a dipyrrinone model for bilirubin. This labeled dipyrrinone was oxidatively coupled to the dimethyl ester of mesobiliverdin-XIII alpha, thereby providing a route to a C-13-labeled mesobiliverdin and mesobilirubin, with one carbon of each ethyl being 98% C-13-enriched.
