    • 13C-NMR SPECTRA OF AZAFLUORENONES 
      Tadic, Dragana; Cassels Niven, Bruce; Laprévote, Olivier; Cavé, André (American Chemical Society, 1988-09-22)
      The 13C-nmr chemical shifts of onychine (l-methyl4-aza8uoren-9-one) [l] were assigned with the aid ofheternnuclear 2D-nmr spectraand these results were used to interpret the 13C nmr spectra of several other synthetic duorenones.

      Tadic, Dragana; Percy Wannigama, G.; Cassels Niven, Bruce; Cavé, André (American Chemical Society, 1986-08-05)
    • REVISED STRUCTURES OF THE AZAFLUORENONE ALKALOIDS FROM GUAITERIA DIELSIANA 
      Tadic, Dragana; Cassels Niven, Bruce; Cavé, André; Goulart, Marília O. F.; De Oliveira, Alaíde B. (Pergamon Journals Ltd., 1986-10-28)
      The structures of three alkaloids isolated from Guatteria dielsiana, 6-methoxyonychine, dielsine and dielsinol, originally described as l-azafluoren-9-ones, are revised to 4-azafluoren-9-ones on the basis of previous synthetic ...
    • SPECTRAL PROPERTIES OF RING-C-OXYGENATED 4-AZAFLUORENES AND 4-AZAFLUORENONES. THE STRUCTURES OF NATURAL ... 
      Tadic, Dragana; Cassels Niven, Bruce; Cavé, André (Elsevier , Science Ltd., 1987-09-30)
      4-Azafluorenes bcaring a methoxy group at C-5, -6, -7 or -8 and a methyl at Col or -3 were synthesized by thermolysis of O-crotyloximes of appropriately substitutcd indan-I-ones. The corrcsponding azalluorenones were ...
