With enough money, patience, and studying, you can accomplish any of those things. Learn the basics of vacuum distillation, fractional distillations, acid base extractions and titrations and the reactions will work themselves out. Most are easy, some very exciting.
In the small scale reductive amination of MDP2P -> MDMA Nitromethane is allowed to react with elemental aluminum. It is very exciting once the reaction takes off as it can get quiet violent depending on the drip rate. For most first timers you can easily shit your pants once the reaction starts rolling along.
2CB is also something of interest and enjoyment to some people. The common first timer route to 2CB will require LAH which is not easy to find, but if you get some, and ever get to check this reaction out.. it's scary. Even on a very small scale. LAH gives out a lot of hydrogen when exposed to water so it's important to dry all your reagents to anhydrous condition.
Also consider hanging out in the federal pen for 10-25yrs. Manufacturing listed compounds when you know little about the reagents needed will prove to be fatal. Acquisition of precursors is not easy these days. I would stick to dro imo. Or so I've heard..
