Here is a representative sample of what I've found so far, I'll also upload the Birch papers later, but anyone with anything by Benkeser, Bedenbaugh, Burgstahler or Kaiser, which adds to what I've put here, please feel free to add 'em

PS As there is now a reasonable, scaleable route to Methcathinone using pretty much OTC materials and no hard to get chems - barring the Li/Amine to reduce it - it is necessary to establish a decent route to enable that reduction to be made feasible on a decent scale. As Li/EtNH2 is a VERY strong reducing combination, I strongly suspect the undivided cell approach may be the best option, but only time and experimenting will tell (why I added the test for overreduced meth - thanks to the DEA we can now know for sure if the product is what we hope it is).
