In an electrolytic reduction of nitrostyrene compounds how do you avoid or promote amine or phenethylamine formation? Like for instance if one were to reduce 3,4,5 trimethoxy-beta nitrostyrene into 3,4,5-TRIMETHOXYAMPHETAMINE(TMA) how would one avoid making it into 3,4,5-TRIMETHOXYPHENETHYLAMINE(mescaline) or vice versa?
Also how do you prevent a beta phenethylamine derivative from 3,4 MD beta nitrostyrene. As MDA is favourable here not a PEA.
