It is a diastereomer of ephedrine, meaning that it has the same basic structure, but its atomic arrangement is different at one of the two stereogenic centers. This practical synthesis is expected to be a disruptive technology replacing the need to find an open pharmacy. Although the above and similar IR absorption tables provide a good starting point for assigning simple IR spectra, it is often necessary to understand in greater detail some more specific properties of IR spectra. Bidentate ligands are often referred to as chelating ligands ("chelate" is derived from the Greek word for "claw") because they can "grab" a metal atom in two places.

BACKGROUND OF THE INVENTION A range of important classes of pharmaceutical compounds, food additives and other biologically active compounds are based on chiral alkyl amines. Ephedra compounds are well known due to their biological activity. Numbers in squares indicate sites of: 1) action of α- and β-adrenoceptor blockers or weight loss medications [phentermine (Adipex, Fastin, Zantryl), phendimetrazine (Bontril, Adipost, Plegine), methamphetamine (Desoxyn), and phenylethylamine (Fenphedra)] as sympathomimetic amines. The compound has received much attention by pharma- cologists because of its action on the central nervous system (2), but despite,its simple chemical structure the biosynthetic origin of its carbon skeleton is still not established. In this paper, a novel enzymatic process was developed for the stereoselective synthesis of (1S, 2S)-ephedrine. Title: The biosynthesis of ephedrine. Soni et al. Valente, Michael C. Customs agents. Stimulating the beta(2)-adrenoreceptors increases protein synthesis and counteracts the catabolism of muscle commonly seen with low calorie diets (10). The most common oxidant used during the synthesis is potassium permanganate (KMnO4). In general, the B—H oxazaborolidines were synthesized following the established condensation reaction of the corresponding chiral 1,2-amino. Ephedrine, L-erythro-1-phenyl-2-methylaminopropanol-1, is synthesized from benzaldehyde in a few different ways. The reduction of (-)-ephedrine by lithium in liquid ammonia resulted in the formation of S-1-(1,4-cyclohexadien-1-yl)-N-methyl-2-propanamine.
