一般描述
(1S,2S)-(+)-Pseudoephedrine, a natural enantiomer of ephedrine, is a decongestant commonly used in cold and allergy medicines.
应用
(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.

We have developed an efficient protocol for carrying out the stereocontrolled formal conjugate addition of hydroxycarbonyl anion equivalents to α,β-unsaturated carboxylic acid derivatives using (S,S)-(+)-pseudoephedrine as chiral auxiliary, making use of the synthetic equivalence between the heteroaryl moieties and the

What's known on the subject? and What does the study add? Modern surgical techniques have allowed preservation of fertility in most patients after post-chemotherapy retroperitoneal lymph node dissection (PC-RPLND), but some patients still have infertility after surgery. We reviewed our
