| titleOfInvention | Alcohol-ester sparation by reaction with acetate |
| abstract | A process is disclosed for the isolation of an enantiomerically enriched alcohol from a first mixture of an enantiomerically enriched 1-arylsulfonate-2 -hydroxy-3-butene and an enantiomerically enriched 1 -arylsulfonate- 2-acyloxy-3-butene. The process includes the steps of: n (a) contacting the mixture with a reagent capable of reacting with said 1-arylsulfonate-2-hydroxy-3-butene to remove the arylsulfonate group and produce a mixture of dihydroxybutene monoesters thereby forming a second mixture containing said dihydroxybutene monoesters and unreacted enantiomerically enriched 1-arylsulfonate-2-acyloxy-3-butene n (b) contacting the second mixture with reagents capable of hydrolyzing all of the acyl groups in said mixture to hydroxy groups so as to produce a third mixture comprising 1,2-dihydroxy-3-butenes and enantiomerically enriched 1-arylsulfonate-2-hydroxy-3 -butene; n (c) washing said third mixture with water so as to remove said 1,2-dihydroxy-3-butenes. |
