Photo-oxidation of bilirubin in hydroxylic solvents: propentdyopent adducts as major products

Abstract

Irradiation (>300 nm) of an oxygen-flushed solution of bilirubin in dilute methanolic ammonia gives a complex mixture including methanol–propentdyopent adducts as major products; one of these, and methylvinylmaleimide have been isolated.
