The alkaloids of Abuta imene and Abuta rufescens

Abstract

The alkaloid fraction of either Abuta imene or Abuta rufescens was found to contain the oxoaporphines imenine, homomoschatoline, and imerubrine, as well as the azafluoranthenes imeluteine, rufescine and norrufescine. Structures are proposed for the new alkaloids imerubrine and norrufescine, and a synthesis of homomoschatoline is described. © 1975.
