Some years ago their was a sudden avalanche of XTC tablets with 250-300mg of material in them. Now, NO producer is going to put in more than they need to and people are not about to pay double... so I had a GOOD look at the current precursors, syntheses and dose-forms. Piperonal, PMK, MDNPe & MDNPa are now almost extinct as precursors; law enforcement has stopped them & it's the people selling high-price but pure powder who snag all that which is still around. Now PMK glycidate is the de facto precursor.
Someone has found what I consider to be a slice of genius - a 1-step route from PMK glycidate to MDMA. Before then, PMK glycidate had to be converted to PMK & reacted with methylamine BUT methylamine has also been clamped down on. Now, PMK is achiral BUT PMK glycidate is chiral so if your 'magic' 1-step synthesis begins with (S) PMK glycidate, your product is (S) MDMA and likewise (R) PMK glycidate yields (R) MDMA. If you take a quick read of the 'MDMA' section of Pihkal, you will discover that (R) MDMA is active, (S) MDMA almost inactive.
The Chinese convert PMK into PMK glycidate via the Darzen's Reaction by reacting it with methyl 2-chloropropanoate. Now, the cheapest way to make methyl 2-chloropropanoate is from methyl 2-hydroxypropanoate which in turn is made from lactic acid.
OK - 2-chloropropanoate, methyl 2-hydroxypropanoate & the starting point, lactic acid, are ALL chiral. If the synthesis is from (S) PMK-glycidate, the product will be (S) MDMA (the less active isomer). Oh, and the natural isomer of lactic acid is natural and so MUCH cheaper..... care to guess WHICH isomer the Chinese use?
I honestly think that the skillset of MDMA chemists has been eroded sufficiently for them not even to know HOW to convert PMK glycidate to PMK. I mean, it's 2 steps BUT you only need to put ⅓ as much material into each pill!
I'm sorry if this has been covered before but it seems that most people still do not understand what is going on. So, as a gift to MDMA lovers everywhere, I offer you 'Empathy', an MDMA mimic that is more euphoric.

We carried out trials right up to stage 2 so hundreds of people tried & loved it. Most were recruited via
www.eunoiapharmacopia.com BUT 5APB & 6APB were cheaper to make. Not simpler - in fact it's easier to get pure Empathy than pure APBs because the latter always had some positional isomers mixed in. Now, I know someone sold p,4-dimethylaminorex as 'Serotonia' and we tried it... and it sucked. You see, the p-Me is a potent SERT inhibitor but it has almost no DAT or NET activity. I'm sure people who tried Serotonia noted how mild it was. So the m-Me is a potent DAT/NET inhibitor. The ratios are designed to match up to the ratio of (R) MDMA. The m-Me alone is just a euphoric stimulant. The p-Me alone is like the crappy MDMA we see today.
I guess you only have my word for it but I am quite confident that Chinese RC manufacturers browse these sites and so they will know if this is true or just me lying. I cannot detail the synthesis but benzaldehyde + nitroalkane ---> nitroalcohol+ NaBH4 ---> aminoalcohol + BrCN ----> product. KOCN doesn't work, you end up with substituted urea.
IF Chinese manufacturers want to provide a good precursor, MD-phenyl-2-nitropropane is legal & can be converted to MDA in 1 step, MDMA in 2 steps. What is cool is that their are DOZENS of reactions that will yield MDA (CTH, complex borohydrides, dissolving metal reductions etc....) and MDA ---> MDMA also has DOZENS of options, all simple.
Oh, and 4MAR is an MAOI, AR is not. I asked David Nichols about that detail and I tend to trust his word.
I will conclude by noting that Empathy was legal when we designed & produced it - no laws were broken... we even paid our taxes.
