Extracurricular laboratory: Synthetic route of 4254-15-3

4254-15-3, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,4254-15-3 ,(S)-Propane-1,2-diol, other downstream synthetic routes, hurry up and to see

It is a common heterocyclic compound, the chiral-oxygen-ligands compound, (S)-Propane-1,2-diol, cas is 4254-15-3 its synthesis route is as follows.

To (S)-propane diol (4.89 g, 64.2 mmol) in DCM (20 ml_) at -20 0C (CO2/ ethylene glycol bath) was added TEA (11.2 ml_, 80.3 mmol) followed by p-toluenesulfonyl chloride (12.3 g, 64.3 mmol) in DCM (26 mL) dropwise over 30 minutes. The cold bath was allowed to expire while stirring for 26h. DCM was added and the reaction was washed with 1 N HCI, water, and brine. The organic layer was dried (MgSO4), filtered, and concentrated in vacuo. The residue was purified by silica gel chromatography (0-40% EtOAc/Hex over 40 minutes) to provide the tosylate (8.37 g, 36 .4 mmol).
