Hi there ppl.

This my first post and i hope i dont get my head blown off

Iv been trying to find the actual detailed Synth for turning L-pac gained from the Bio transformation fermentation process into lephedrine but cant find a decent tek to explain..!
i did a quick search on this forum and another i abandoned tonight,
i may have found something on this forum, but been awake for way to long,that i dont have time to check. 
its my greek easter and i have to go, otherwise ild be looking for hours more )
most posts talk about the actual fermentation and less about the conversion, and when i thought i found it, it turned out to be lpac---> (PPA) (i think), Im sooo tierd i cant even remember the intertwining names , im not usually so lazy but i seriusly been sitting here 12 hours scouting, for a conversion method,
actually i think i did find one, but not the one i was after,

I dont want to be spoon fed the info, i just thought since i made an acc here ild give the experts a chance to lay it out as clearly as possible to help me out, I saw a method i think which used palladium as a catalyst, but i want the most simple tek to start with, like i said im not an expert, i just wanna learn.
n if i cant find it im sure other haveing problems, unless iv just went into over drive last night and confused myself

i dont care bout conversion rates at the moment, just want to practice and get my hands dirty.

So yea, if anyone can help with a good method,or gimmie a few to check out n see for myself which suits my situation best.  ild be grateful,


Sorry for not putting in more time but like i said im pooped,
Thanks

Peace

Look this pdfs

I looked though scimad for 6 hr b4 i came here 

for whatever reason i couldn't find the diff methods for specific reactions.
I know it can be reduced but i want to see which synth would be best for my situation.

Eaither way, i was expecting the UTTFSE,
 im sorry but thanks alot, lugh

Worst case, for the next me that comes along its all there

peace

Please stop with the post-whoring in this part of the forum. If you really must build up your posts, this is not the section to be doing that in.

With regard to SM, please don't bother using their search engine - it is worse than useless because there are far too many worthless posts clogging fuck out of it. Instead use the "site:http:www.sciencemadness.org ..." in google - put whatever you want to search for after that (Please don't tell me you cannot find l-pac related material on SM using that tip - there is one MAJOR contributor to the l-pac discussions on SM that is also on this board). If you actually do the work, I'd almost expect them to help you out.

Thanks mate, its not that i dident find any info on it, its just i found too much info on it ;/ if you know what i mean,

Thanks for the tip tho and offer, time to do some studying.

Peace,
And post whoring was the furthest thing on my mind, was just saying thank you for the links.

Hi.

I want to ask from what Ephedrines are commonly used in pharmacy.
Otherwise, the more I want to make sure whether the PAC-L -> (-)-Ephedrine -> (+)-PSEUDO -> d-Meth? synthesis

 In my opinion you used not enough catalyst to hydrogenate the whole L-PAC. And in your 2nd Hydrogenation you upscaled the catalyst but also you've doubled the amount of L-PAC so it is in my opinion clear that the yield not as good as it could.

Because in your patent they use 15 parts of platinised Raney Nickel to 10 parts of L-PAC and i think you mixed it up, so you have not enough catalyst to hydrogenate the whole L-PAC to ephedrine.

......its arguable as to the perfect ratio , most would say mole/mole...but her is a thread for you to read...java
