摘要:The invention relates to a process for the electrochemical synthesis of alkali metal alcoholates (alkoxides) and/or for the regeneration of the catalyst from methyl formate synthesis from alcoholic solutions of salts of alkali metals in an electrolysis apparatus with an ion-selective membrane. The electrolysis is carried out in the presence of a defined quantity of a potassium salt or sodium salt of a perfluoroalkanesulphonic acid accompanied by the use of non-oxidisable anode material and with a membrane based on a sulphonated styrene-divinylbenzene copolymer. The process enables an increase in the selectivity of the procedure and a continuous synthesis.

摘要:A chiral bimetallic cooperative catalysis system and use thereof in asymmetric synthesis of bedaquiline are provided. Specifically, the chiral bimetallic cooperative catalysis system is formed by a metallic lithium, sodium or potassium salt and another metal salt under the action of a suitable ligand and an additive. By means of the chiral bimetallic cooperative catalysis system, an addition reaction of 6-bromo-3-benzyl-2-methoxyquinoline (I) and 3-dimethylamino-1-naphthyl-1-propanone (II) is promoted, the selectivity is regulated, and a target product, (1R,2S)-bedaquiline, with high yield and high selectivity is obtained for the first time.

摘要:An improved method for the synthesis of the anticancer drug picoplatin is provided. Condensation of a tetrachloroplatinate salt (TCP), such as potassium tetrachloroplatinate, and 2-picoline, in a solvent, is catalyzed by the presence of oxygen, such as in air, and additionally catalyzed by the presence of a Pt +4 complex, such as potassium hexachloroplatinate. The oxygen can be introduced into the reaction mixture by sparging, optionally with high shear mixing and under an inert gas headspace. The product trichloropicolineplatinate salt (TCPP) is a key intermediate in the synthesis of picoplatin, to which it can be converted by reaction of the TCPP with ammonia.
