Abstract
Characterization of MDA (3,4-methylenedioxyamphetamine) and a series of nitrogen-substituted MDA analogues has been studied using proton and carbon-13 NMR spectroscopy. The 1H and 13C chemical shift assignments for both have been confirmed using a combination of 1-dimensional and 2-dimensional NMR experiments. The chemical shift trends of the side chain carbon resonances ((https://www.thevespiary.org/rhodium/Rhodium/hive/hiveboard/picproxie_docs/000435812-file_lwwo.gif)-CH2, (https://www.thevespiary.org/rhodium/Rhodium/hive/hiveboard/picproxie_docs/000435812-file_feqa.gif)-CH, and (https://www.thevespiary.org/rhodium/Rhodium/hive/hiveboard/picproxie_docs/000435812-file_xegs.gif)-CH3) for MDA, N-methyl MDA and N,N-dimethyl MDA, as both free bases and hydrochloride salts, have been examined.
