      proton nmr shift values for some compounds??  Bookmark   

hi :D ... ive searched the lit but i cant find some nmr details for many things... i have many.. but many i dont... does anyone have shift values for mda, mdma? i have suitable reference spectra for the precursers.. but the goodies have been a little difficult to come by...

appreciate your help.

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 (-CH2, -CH, and -CH3) for MDA, N-methyl MDA and N,N-dimethyl MDA, as both free bases and hydrochloride salts, have been examined.
