| titleOfInvention | METHOD FOR ALCOHOL / ESTER SEPARATION USING PROTECTED HYDROXYL GROUPS. |
| abstract | The invention relates to a method for separating an enantiomerically enriched alcohol from a first mixture of an enantiomerically enriched alcohol and an ester. The process comprises the following stages: (a) bringing the mixture into contact with a reagent capable of reacting with the hydroxy function of the alcohol, without reducing optical purity, so as to produce a second mixture containing a derivative stable to bases of the enantiomerically enriched alcohol and the unreacted ester; (b) bringing the second mixture into contact with a base capable of reacting with the ester so as to produce a third mixture containing a compound more volatile than the stable derivative based on alcohol; (c) removing the volatile compound from the third mixture; and (d) the retransformation of the alcohol-based stable derivative into an enantiomerically enriched alcohol without decreasing optical purity. |
