Use | P-methamphetamine is a chemical reagent used in electrocarboxylation reactions. The intermediate of Naomaining. |
application | p-methamphetamine is a pharmaceutical naomaining intermediate, which can be used as an organic synthesis intermediate and a pharmaceutical intermediate, and is mainly used in laboratory research and development processes and chemical production processes. |
synthesis method | using chiral adsorption inducer alkaloids to induce the electrosynthesis of α-7, radical-α-hydroxy -4-methyl-phenylacetic acid by immobilizing carbon dioxide with methamphetamine. The higher yield and certain ee value are measured by constant current electrolysis and high performance liquid phase gun. The electrode material, current density, inducer and other factors of the reaction are preliminarily investigated, it is found that in annular stainless steel as cathode, magnesium rod as sacrificial anode, tetrabutylammonium iodide as electrolytic support salt, O.016g cinkoning as inducer and temperature of 0 ℃, yield 37.39% and ee value S-32.78%. |
