(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.
