    • Determination of acid dissociation constants of anomers of amino sugars by 1H NMR spectroscopy 
      Blasko, Andrei; Bunton, Clifford A.; Bunel Torrealba, Sergio; Ibarra, Carmen; Moraga, Exequiel (Elsevier Science Publishers B. V., 1997)
      Acid dissociation constants of α- and β-D-glucos-, mannos-, and galactos-ammonium ions have been determined from 1H NMR chemical shifts of the individual anomers in D2O. Values of pKa(D) for the α- and β-ammonium ions ...
    • New aldehydes by catalytic diene cycloisomerisations 
      Grau, Fanny; Bayón, J.; Aguirre, Pedro; Parella, Teodor; Duñach, Elisabet (2008)
      The Rh-catalysed hydroformylation of isopropylidenecyclohexane derivatives obtained by intramolecular diene cyclisations affords the corresponding aldehydes in good yields and in a completely chemo- and regioselective ...
