Each of the enantiomers of both norephedrine and norpseudoephedrine were stereoselectively prepared from the common, prochiral cyclic sulfamidate imine of racemic 1-hydroxy-1-phenyl-propan-2-one by employing asymmetric transfer hydrogenation (ATH) catalyzed by the well-defined chiral Rh-complexes, (S,S)- or (R,R)-Cp*RhCl(TsDPEN), and HCO(2)H/Et(3)N as

Here we contrast the vascular smooth muscle contractility produced by D-nor-pseudoephedrine, alone or combined with triiodothyronine, on the aorta and coronary vasculature of the rat. At high concentrations (greater than those found in normal therapeutic dosing) D-nor-pseudoephedrine contracted the aorta.

The use of a single internal standard (ephedrine-d5) as the basis for calculations of the concentrations of both the major and the minor alkaloids leads to incorrect results from variabilities in the solid-phase extraction (SPE) of the ephedra alkaloids. Because
