7-Oxoaporphine alkaloids

The oxoaporphine alkaloids Teliglazine (126), Corunnine (127), Nandazurine (128), PO-3 (129), A-Methylliriodendronine (130), and A,(9-Dimethylliriodendronine (131) contain the 6-methyl-7-oxo-dibenzo [Je,g]quinolinium-l-olate ring system 125 which is isoconjugate with the l-methyl-7-methylene-7H-benzo[Je]anthracene anion (Scheme 46). Therefore, these alkaloids belong to class 1, i.e., heterocyclic mesomeric betaines isoconjugate with odd alternant hydrocarbon anions. Another... [Pg.108]

Reissert alkylation and Pschorr cyclization have frequently been utilized for the synthesis of oxoaporphine alkaloids by Cava and co-workers. Their synthetic... [Pg.15]

The mass spectra of 4,5-oxoaporphine alkaloids are characterized by a direct loss of CO (M — 28) from the molecular ion (base peak) leading to a prominent peak at miz 265 (27%). Subsequent loss of a methyl group accounted for the other significant peak at mIz 250 (51%) (64). [Pg.38]

N,O-DimethyIIiriodendronine (95), isolated in fairly large amounts from G. chrysopetala (21), stands out among the oxoaporphine alkaloids found in Guat-teria in that it is a zwitterion related to the highly colored compounds of Glau-cium (Papaveraceae). Neutral and basic solutions of the rather insoluble N.O-... [Pg.36]

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 Reissert compound has been prepared from 9-methoxyellipticine and both it and 10 give a fluoroborate salt of the type 19. The Reissert compound of 6,7-dimethoxyphthalazine has been used to prepare an azapa-paverine. The oxoaporphine alkaloid subsessiline has been synthesized using the Reissert compound of 5,6,7-trimethoxyisoquinoline. The reaction of vanillin Schiff bases with benzoyl cyanide yields open-chain analogs of Reissert compounds. a-Acylaminonitriles, which can be considered as open-chain Reissert compounds, have been converted to open-chain analogs of Reissert salts (5-imino-3,5-dihydrooxazole derivatives). - ... [Pg.214]

The oxoaporphine alkaloid pontevedrine stands apart from these two subgroups. Its unique feature is that it possesses an A-methyl pyridone moiety. [Pg.226]

A new oxoaporphine alkaloid, found in Ahuta imene Eichl. (Menis-permaceae), is 0-methylmoschatoline (27 CigHigO N) 54). [Pg.262]
