    • Bond Fukui Functions As Descriptor of the Electron Density Reorganization in pi Conjugated Systems 
      González Suárez, M.; Aizman, Arie; Soto Delgado, Jorge; Contreras Ramos, Renato (AMER CHEMICAL SOC, 2012-01-06)
      The bond Fukui function is introduced and tested as a new reactivity index capable of predicting the evolution of bond breaking and formation processes during an organic reaction involving pi conjugated systems. As an ...
    • Nucleophilicity scale for n- and pi-nucleophiles 
      Jaramillo, Paula; Fuentealba Rosas, Patricio; Pérez López, Patricia (ELSEVIER, 2006-08-31)
      A recently introduced empirical nucleophilicity index for a series of n- and pi-nucleophiles was evaluated. The index is based on the frontier molecular orbital information of the nucleophile and its electrophilic partner. ...
    • Reactivity of the carbon-carbon double bond towards nucleophilic additions. A DFT analysis 
      Domingo, Luis R.; Pérez López, Patricia; Contreras Ramos, Renato (PERGAMON-ELSEVIER SCIENCE LTD, 2004-07-26)
      The global and local electrophilicity indexes have been used to characterize the reactivity pattern of the C=C double bond towards nucleophilic addition reactions. A wide family of molecules including ketones, esters, ...
    • Synthesis of 3-aminolactams as X-Gly constrained pseudodipeptides and conformational study of a Trp-Gly surrogate 
      Ecija, Marta; Diez, Anna; Rubiralta, Mario; Casmitjana, Nuria; Kogan Bocian, Marcelo; Giralt, Ernest (AMER CHEMICAL SOC, 2003-12-12)
      3-Amino-delta-valerolactams trans-11a-c were synthesized through conjugate addition and Curtius rearrangement and converted into Fmoc-{Trp-Gly}, Fmoc-{Ile-Gly}, and Fmoc-{Phe-Gly} pseudo-dipeptides. Conformational analyses ...
