权利人:SEPRACOR INC
摘要:A process for the preparation of optically active cyclohexylphenylglycolate esters is described. The process utilizes carboxylic acid activation to couple (R)- or (S)-cyclohexylphenylglycolic acid (CHPGA) with 4-N,N-diethylamino butynol or other propargyl alcohol derivatives. The preparation of the hydrochloride salt is also described. In addition, a resolution process employing tyrosine methyl ester enantiomers for preparing a single enantiomer of CHPGA from racemic CHPGA is disclosed.

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.

标 题:Uncatalyzed synthesis of symmetrical dicarbonates
发明人：FRANKLIN RALPH
权利人:AKZO NV
摘要:A dialkyl dicarbonate is prepared by contacting an alkyl haloformate with an alkali metal carbonate in the presence of a solvating amount of a solvent. The process of the invention does not require a catalyst, is easy to carry out, does not employ particularly hazardous materials, does not require cumbersome purification steps, and provides a high yield of dicarbonate.
