一般說明
(1S,2S)-(+)-Pseudoephedrine, a natural enantiomer of ephedrine, is a decongestant commonly used in cold and allergy medicines.
應用
(1S,2S)-(+)-Pseudoephedrine condenses with N,N-diisopropyl-2-formyl-1-naphthamide to form the corresponding oxazolidine derivative as a single diasterisomer.
(1S,2S)-(+)-Pseudoephedrine may be used as a chiral auxillary in asymmetric synthesis of enantioenriched organic compounds. It may also be used to prepare a novel tertiary pseudo C2-symmetric 1,2-diamine, which facilitates the enantioselective addition of methyl lithium to imines with better yield.

Clandestine laboratory operators commonly extract ephedrine and pseudoephedrine-precursor chemicals used to synthesize methamphetamine-from over-the-counter cold/allergy/sinus products. To prevent this activity, two states, Oregon in 07/2006 and Mississippi in 07/2010, implemented regulations classifying ephedrine and pseudoephedrine as Schedule III substances, making
