    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.
  • San Martín, Aurelio; Astudillo, Luis; Gutiérrez, Margarita; Chamy, María Cristina; Orejarena, Silvia; Rivera, Patricio; Vergara, Karen (2010)
    In addition to the known diterpenes, desoxyarticulin and dihydrotucumanoic acid, a new neoclerodane diterpene was isolated from Baccharis marginalis. The structures of the compounds were elucidated by spectroscopic evidence.
  • Valenzuela, V.; Santander, P.; Camargo, C.; Squella, J. A.; López Alarcón, Camilo Ignacio; Núñez Vergara, Luis J. (TAYLOR & FRANCIS, 2004-07)
    In the present paper, a direct quenching of radical species by a number of synthesized nitrosoaryl 1,4-dihydropyridines and their parent nitroaryl 1,4-dihydropyridines was determined in aqueous media at pH 7.4. These two ...
  • Izquierdo, S.; Kogan, M.; Parella, T.; Moglioni, A. G.; Branchadell, V.; Giralt, Ernest; Ortuño, R. M. (AMER CHEMICAL SOC, 2004-07-23)
    The efficient synthesis of tetrapeptide 5 containing, in alternation, cyclobutane and beta-alanine residues is described. NMR experiments both at low temperature in CDCl3 and at 298 K in DMSOd(6) solutions show the ...
