As a common heterocyclic compound, it belongs to chiral-oxygen-ligands compound, name is (S)-Propane-1,2-diol, and cas is 4254-15-3, its synthesis route is as follows.,4254-15-3
To a solution of (S)-1,2-propanediol (20.0 g, 0.263 mol), triethylamine (31.9 g, 0.315 mol), 4-dimethylaminopyridine (1.28 g, 10.5 mmol) in CH2Cl2 (200 mL) was added tert-butyldimethylsiloxy chloride (47.3 g, 0.315 mol) at 22 C. The mixture was allowed to stir for 18 h. The mixture was diluted with CH2Cl2, washed with water and sat. aqueous NH4Cl. The organic solution was dried over Na2SO4, filtered and concentrated under reduced pressure. Silica gel chromatography (5% ethyl acetate/hexanes) of the concentrate gave 45.0 g of the title compound as a clear oil in 90% yield.
With the complex challenges of chemical substances, we look forward to future research findings about 4254-15-3,belong chiral-oxygen-ligands compound
