1H nuclear magnetic resonance study of the deprotonation of the catecholamines in solution: the microconstants for the de-deuteronation of L-dopa in D2O
Abstract
The use of pulsed Fourier transform 1H n.m.r. spectroscopy has been shown to give detailed information concerning the protonation sites of the catecholamines; in particular, a method for the assignment of the microconstants for the deprotonation of L-dopa and the determination of their values has been rigorously established.
