- Ephedrine and pseudoephedrine are structurally mirror images of
- each other. This is possible because they have a chiral center, the
- isopropyl carbon to which the nitrogen atom is attached. If the
- reduction is done in such a manner that the chiral nature of the
- substance is not jumbled (i.e. racemization), then ephedrine and
- pseudoephedrine give rise to "l" and "d" methamphetamine, respectively.
- The "l" form is several times more potent than the "d" form. Meth
- produced from phenylacetone is a racemic mixture, meaning that it is
- a 50-50 mix of the "l" and "d" forms of meth. Obviously, a batch of
- pure "l" form is most desireable, a racemic mixture is OK, and pure
- "d" form is bad news.
-
- "Uncle Fester" needs to do more research. l-ephedrine does give rise to the
- more potent *d* form of methamphetamine. both OTC ephedrine and
- pseudoephedrine should be useful for the synthesis (provided that it is
- d-pseudoephedrine which is sold OTC -- which is the natural isomer).
-
- My guess is that Fester extrapolated from using "l-ephedrine" to getting
- "l-methamphetamine" which is quite wrong...
-
- I'm not terribly impressed with this guy...
