The chemistry of pyrrolic compounds. LIV. The chemistry of rhodins, verdins and related compounds

Abstract

Coprorhodin II trimethyl ester has been prepared and its chemical and spectroscopic properties examined. Autoxidation of coprorhodin yields coproverdin while reduction with sodium borohydride affords a secondary alcohol which readily dehydrates under aerobic conditions to furnish a benzo-chlorin. The chemistry of these derivatives of coprorhodin has been studied.
