Synthesis of the reported structures for kealiinines B and C.

Joseph B Gibbons1, Keith M Gligorich, Bryan E Welm, Ryan E Looper.   

Abstract

Syntheses of the reported structures of kealiinines B and C have been executed. An intermolecular electrophile-induced cyclization of a pendant arene on an ene-guanidine affords the tetracyclic, oxidized naphthimidazole cores.
