Oxidative decarboxylation of amino acids into nitriles was performed using molecular oxygen as terminal oxidant and a heterogeneous ruthenium hydroxide-based catalyst. A range of amino acids was oxidized in very good yield, using water as the solvent. This journal is
Method for synthesizing drug intermediate

Paragraph 0038; 0039, (2016/10/10)
The invention discloses a method for synthesizing a drug intermediate. Cyano-acetate and 3,5-bis(trifluoromethyl) halogenobenzene are dissolved in a solvent and have a decarboxylation cyanomethylation reaction under the action of a palladium catalyst and an organic phosphorus ligand to obtain 2-(3,5-bis(trifluoromethyl phenyl) acetonitrile, then 2-(3,5-bis(trifluoromethyl phenyl) acetonitrile reacts with a methylation reagent to obtain 2-(3,5-bis(trifluoromethyl phenyl)-2-methyl propanenitrile, and finally cyano groups are converted into carboxyl groups with alkali to obtain the target product. The method for synthesizing the drug intermediate is easy to operate, raw materials are cheap and easy to obtain, synthesis is easy, side reactions do not happen, and the yield is high.

Bromide-assisted electrochemical decarboxylation efficiently produces valuable nitriles in high yields from a wide range of naturally occurring amino acids in a single step. Bromide salts are used as both redox mediators and supporting electrolytes in a simple one-compartment setup. As demonstrated for lysine, the selectivity of the decarboxylation can be tuned towards nitriles, amines or amides. An electrochemical system is developed that allows the selective decarboxylation of a wide range of amino acids. Valuable nitriles are obtained in high yields in a single step by using bromide salts as both redox mediators and supporting electrolytes. The product selectivity of lysine can be tuned towards nitriles, amines, or amides.
