Abstract

Both enantiomers of pseudoephedrine glycinamide [(+)-or (−)-1] were synthesized by either of two procedures:(1) a standard two-step coupling of N-Boc-Gly with pseudoephedrine followed by deprotection, or (2) a more economical one-step coupling reaction of Gly-OMe with pseudoephedrine mediated by LiCl and base.
