Skiles JW, Saa JM, Cava MP 1979 Splendidine, a new oxoaporphine alkaloid from Abuta rufescens Aublet. Can J Chem 57 1642-1646... [Pg.1156]

A new oxoaporphine alkaloid is oxostephanine (38) from Stephania japonica. Imerubrine, found together with a variety of oxoaporphines and azafiuoranthenes in the South American vines Abuta imene and A. rufescens has been tentatively... [Pg.162]

The unusual alkaloids imeluteine (99) and rufescine (100), found in Abuta imene and A. rufescens, probably originate biogenetically from decarbonylation of oxo-aporphine precursors. Such an in vivo pathway is supported by the observation that Abuta imene also produces the oxoaporphine homomoschatoline (1,2,3-trimethoxyoxoaporphine). It is unlikely, on the other hand, that azafluoranthenes... [Pg.187]

Azafluoranthenes.—Two alkaloids of a novel type are imeluteine (234) and rufescine (235), isolated from the Amazonian vines Abuta imene and A. rufescens (Menispermaceae). The structures of both alkaloids were confirmed by synthesis using the Bischler-Napieralski and Pschorr sequences. [Pg.168]
