Name is (S)-Propane-1,2-diol, as a common heterocyclic compound, it belongs to chiral-oxygen-ligands compound, and cas is 4254-15-3, its synthesis route is as follows.,4254-15-3
(S)-(+)-1,2-propanediol (2.506 g, 32.9 mmol) and 4-methylbenzene-1-sulfonyl chloride (6.91 g, 36.2 mmol) in dichloromethane (DCM) (80 mL) Medium solution,Triethylamine (6.89 mL, 49.4 mmol),Subsequently 4-dimethylaminopyridine (0.201 g, 1.647 mmol) was added.The reaction was stirred at room temperature for 16 hours.The reaction was quenched with saturated aqueous ammonium chloride (20 mL) and the layers were separated.Extract the aqueous portion with DCM (2 ¡Á 20 mL),The combined organic layers were washed with saturated aqueous sodium bicarbonate (20 mL) and brine (20 mL).The organic portion is dried over MgSO4, filtered,Concentrate under reduced pressure to give a residue that isPurification by silica gel chromatography eluting with 10-100% ethyl acetate: heptane gave the product (4.56 g, 60% yield).
With the complex challenges of chemical substances, we look forward to future research findings about (S)-Propane-1,2-diol
