Methamphetamine/amphetamine metabolites and prodrugs, potential conversions

[UrbyDOPE]

Hello I would like to discuss potential methods of conversion of Methamphetamine/Amphetamine prodrugs such as: amphetaminil, benzphetamine, clobenzorex, deprenyl, dimethylamphetamine, ethylamphetamine, famprofazone, fencamine, fenethylline, fenproporex, furfenorex, mefenorex, mesocarb, and prenylamine

Is there any documented method of conversion any of these prodrugs into dextromethamphetamine and/or dextroamphetamine in vitro?

Is there documented any simple method of preparation any of these prodrugs?
