    • 1-Benzyl-1,2,3,4-tetrahydroisoquinolines. 1H NMR conformational studies and rotational barriers 
      Iturriaga-Vásquez, Patricio; Zapata-Torres, Gerald; Rezende, Marcos Caroli; Cassels Niven, Bruce (2004)
      The conformational preferences of a series of 1-benzyl-1,2,3,4- tetrahydroisoquinolines (norlaudanosine and coclaurine analogues) were investigated with the aid of their 1H NMR spectra and NOESY experiments, coupled with ...
    • A novel route to 5,7-dimethoxy-6-hydroxyflavone 
      Osorio-Olivares, Mauricio; Cassels Niven, Bruce; Sepúlveda-Boza, Silvia; Rezende, Marcos Caroli (Marcel Dekker Inc., 1999)
      A novel route to 5,7-dimethoxy-6-hydroxyflavone is described, involving the cyclization of an intermediate phosphorane as the key step.
    • Alkylated benzodithienoquinolizinium salts as possible non-fullerene organic n-type semiconductors: an ... 
      Aracena, Andrés; Rezende, Marcos Caroli; García, Macarena; Muñoz Becerra, Karina; Wrighton Araneda, Kerry; Valdebenito, Cristian; Celis, Freddy; Vásquez, Octavio (MDPI, 2021)
      Three photobicyclized benzodithienoquinolizinium tetrafluoroborates (BPDTQBF4) were prepared and evaluated by UV–Vis and fluorescence spectral, electrochemical analysis, and by theoretical calculations as possible organic ...
