The most common method of manufacture of methamphetamine in the United States is the reduction of ephedrine with hydriodic acid and red phosphorus (HI/red P) 1. Pseudoephedrine and ephedrine are commonly obtained from pharmaceutical preparations, which are often available from drug stores or pharmacies “Ephedrae herba” is an important crude drug in Kampo prescriptions and ephedrine (EP), its main constituent, shows potent antitussive activity [ 1 ]. Third, pseudoephedrine was demonstrated to be recoverable from multi-ingredient, liquid, and/or softgel over-the-counter A novel and efficient approach to chiral tetrahydroquinolines with excellent enantioselectivities and high yields has been described via one-pot cascade biomimetic reduction. Conducted based on the officers’ first-hand experience, the test showed that meth cannot be made with Zephrex-D® using the “one pot shake and bake” process. The prepared nano-adsorbents based on GO in this study were coated by 1) Iodine (13g), pseudoephedrine (10g), and red Phosphorus (4g). In addition to the reduction of the aromatic ring, the Pseudoephedrine is a light stimulant in comparison to for example aphetamines. It describes the key ingredients (pseudoephedrine, lithium metal, and anhydrous ammonia) and how they are obtained. Furthermore, the detaile Our interest in phosphine(V) oxides reduction originates from our desire to explore bulky N-phosphinomethyl-functionalized N-heterocyclic carbene ligands (NHCPs) 80, 81 as potential ligands for new olefin metathesis catalyst (Scheme 2).
