Abuta rufescens

Splendidine (37), a new oxoaporphine, has been obtained from Abuta rufescens Aublet ( = A. splendida) (Menispermaceae). Following its structural elucidation, its total synthesis was achieved via a Reissert-Pschorr sequence The known phenolic oxoaporphine subsessiline, found in a Guatteria species (Annonaceae), has been established to possess structure (39) instead of the... [Pg.133]

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]

A new azahuoranthene alkaloid, produced by Abuta imene and A. rufescens, is the phenolic norrufescine (47). ... [Pg.166]

The Tetitoxicum genus is closely related to some Abuta species such as A. imene and A. rufescens based on the constituents present which are mainly oxoaporphines and azafluoranthenes. It is possible dial 4,5-dioxoaporphines may also be present in some of these Abuta species. [Pg.283]

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]
