摘要:The present invention generally relates to the individual stereoisomers of the drug valnoctamide (a mixture of four stereoisomer kinds, VCD-valmethamide or 2-ethyl-3-methyl pentanamide) useful in treatment of neurological and psychotic disorders such as different kinds of epilepsy and affective disorders, and useful as tranquilizers and to treat pain, and to pharmaceutical compositions containing, as an active ingredient, these stereoisomers. The present invention further relates to a method for stereoselective separation and quantification of the four stereoisomers from a racemic mixture of VCD or plasma of patients treated with the racemic drug. The present invention further relates to a unique method for the synthesis of the individual stereoisomers.

标 题:Online continuous flow process for the synthesis of organic peroxides using hydrogen peroxide as raw material
发明人：MA BING; PAN SHUAI; SHU XINLIN
权利人:SHANGHAI HYBRID CHEM TECH
摘要:An online continuous flow production process for directly preparing organic peroxides by using hydrogen peroxide as a raw material. This production process uses hydrogen peroxide, catalyst, and an oxidation substrate as a raw material. Substrate will be turned to designated peroxides sequentially through oxidation and workup. This process is performed in a plug-and-produce integrated continuous flow reactor, and the raw materials are continuously fed to the reactor. So, specified peroxide can be continuously obtained at the outlet of the plug-and-produce integrated continuous flow reactor.
