Graphical abstract: Highlights: Lipase TL®-mediated kinetic resolution of glycerols proceeded efficiently at −5 °C. High enantiomeric excess and quantitative yield. Efficient convergent route to both enantiomeric glycerol units. Abstract: In the presence of pyridine, at −5 °C, lipase TL®-mediated kinetic resolution of (±)-1-(( tert -butyldimethylsilyl)oxy)-3-((4-methoxybenzyl)oxy)-propan-2-ol was found to proceed efficiently to give the corresponding ( S )-alcohol and ( R )-acetate, each with high enantiomeric excess and in quantitative yield. The alcohol ( S )-1 and the acetate ( R )-2 -derived alcohol, ( R )-1, could be converted to the 1-protected glycerols with either of the stereochemistry by the choice of the deprotection of the protective groups.
