  • 2D 1H and 13C NMR conformational studies of thienopyridines and carboline biarylic compounds 
    Corona Becerril, David; Díaz Torres, Eduardo; Barrios López, Héctor; Sánchez Mendoza, Ernesto; Alvarado, C; Jankowski, Christopher; Guzmán, Ángel (Elsevier Ltd, 2009-06-30)
    In this paper, we report on conformational studies of biarylic compounds, as prepared through the well known aza-Wittig methodology. The conformational studieswere mainly realized by bidimensional (2D) nuclear magnetic ...
  • Long range 1He19F coupling through multiple bond in thienopyridines, isoquinolines and 2-aza-carbazoles derivatives 
    Silva Nigenda, Ezequiel; Mártínez Gómez, Alejandro; Cruz de la Cruz, Janneth; Barroso Flores, Joaquín; González Romero, Carlos; Benites Fuentes, María Paulina Aydeé Gracia; Jankowski, Christophe K.; Cuevas Yáñez, Erick; Díaz Torres, Eduardo; Corona Becerril, David (Journal of Molecular Structure, 2018-08-28)
    Long range 5J and 6J (1H-19F) spin-spin coupling constants for a set of nine biarylic fluorinated derivatives were determined by 1H NMR experiments. The quantitation of these long-range 5J and 6J (1H-19F) coupling can ...
  • Synthesis of 4,5,6,7-tetrahydrobenzoxazol-2-ones by a highly regioselective Diels-Alder cycloaddition of exo-oxazolidin-2-one dienes with chalcones 
    Mastachi Loza, Salvador; Ramírez-Candelero, Tania I.; Tapia Bustamante, Asenet; González Romero, Carlos; Díaz Torres, Eduardo; Tamariz, Joaquín; Toscano, Rubén A.; Fuentes Benítes, Aydeé (Tetrahedron Letters, 2019-05-16)
    The synthesis of novel of 4,5,6,7-tetrahydrobenzoxazol-2-ones is herein reported. They were obtained in moderate to good yields by a highly regio- and stereoselective Diels-Alder cycloaddition of N-substituted exo-oxazolidin-2-one ...
