| | (S)-(-)-2-ACETOXYPROPIONYL CHLORIDE Usage And Synthesis |
| Uses | Frequently used chiral building block. Also used to resolve a bicyclic α-hydroxylactone and to prepare chiral phosphonates used in an enantiomeric excess assay of unprotected amino acids. Useful chiral derivatizing agent. | | Purification Methods | It is moisture sensitive and is hydrolysed to the corresponding acid. Check the IR spectrum. If the OH band above 3000cm -1 is too large and broad then the mixture should be refluxed with pure acetyl chloride for 1hour, evaporated and distilled under reduced pressure.
