    • Crystal structure of 4-[(adamantan-1-yl)amino]naphthalene-1,2-dione 

      Lamoureux Lamontagne, Guy; Pineda Cedeño, Leslie William; Alvarado Rojas, Mónica (2019)
      The title compound, C20H21NO2, an example of a stable 1,2-naphthoquinone, was determined by single-crystal X-ray diffraction analysis at 100 K. This structure illustrates steric buttressing of the adamantanyl group, forcing ...
    • Efficient syntheses of streptocarpone and (±)-a-dunnione 

      Pérez Sánchez, Alice Lorena; Lamoureux Lamontagne, Guy; Sánchez Kopper, Andrés (2007)
      An efficient divergent synthesis of both streptocarpone and racemic α-dunnione from lawsone are described. A one-pot, formal [3+2] cyclization to form a furanonaphthoquinone directly provided a common intermediate.
    • Reactivity and structure of derivatives of 2-hydroxy-1,4-naphthoquinone (lawsone) 

      Lamoureux Lamontagne, Guy; Pérez Sánchez, Alice Lorena; Araya Marchena, Mario Esteban; Agüero Robles, Christian Gerardo (2007-11)
      The structures of two derivatives of 2-hydroxy-1,4-naphthoquinone (lawsone) are examined using the density functional theory (DFT) hybrid functional B3LYP. Using the optimized structure of lawsone acetate, the reactivity ...
    • Synthesis and biological evaluation of novel ferrocene–naphthoquinones as antiplasmodial agents 

      García Barrantes, Pedro M.; Lamoureux Lamontagne, Guy; Pérez Sánchez, Alice Lorena; García Sánchez, Rory N.; Martínez, Antonio R.; San Feliciano, Arturo (2013-12)
      This work deals with the synthesis and evaluation of new compounds designed by combination of 1,4-naphthoquinone and ferrocene fragments in a 3-ferrocenylmethyl-2-hydroxy-1,4-naphthoquinone arrangement. A practical coupling ...
    • Synthesis of 2-hydroxy-3-substituted naphthoquinones using the Heck reaction 

      Pérez Sánchez, Alice Lorena; Lamoureux Lamontagne, Guy; Zhen-Wu, Bi Yun (2007-06)
      An efficient Heck coupling of 2-hydroxy-3-iodo-naphthoquinone with a series of electron-deficient alkenes in aqueous solution has been accomplished. The method is characterized by simple conditions and facile work-up to ...
