Determination of acid dissociation constants of anomers of amino sugars by 1H NMR spectroscopy
(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 ...
Experimental NMR and MS study of benzoylguanidines. Investigation of E/Z isomerism
(2013-04-01)
Molecules containing the guanidinic nuclei possess several pharmacological applications, and knowing the preferred isomers of a potential drug is important to understand the way it operates pharmacologically. Benzoylguanidines ...
