Descrizione generale

(1S,2S)-(+)-Pseudoephedrine, a natural enantiomer of ephedrine, is a decongestant commonly used in cold and allergy medicines.

Applicazioni

(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.

Azioni biochim/fisiol
