Other Notes
Esters of enantiomerically pure lactic acid are used as starting material for the synthesis of many interesting chiral building blocks, e.g. (R)-1,2-propanediol by reduction with LiAlH41; (R)-2-alkoxypropanol by O-protection and reduction2; (R)-propylene oxide3; (R)-2-acetoxypropionyl chloride4; (R)-2-O-tosyl-1,2-propanediol5
