A common heterocyclic compound, 24621-61-2,(S)-Butane-1,3-diol, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route. 24621-61-2
The flask was charged with (S) -butane-1,3-diol (1.00 g, 11.10 mmol) in dichloromethane (DCM) (27 mL),Triethylamine (1.347 g, 13.32 mmol),4-Dimethylaminopyridine (0.136 g, 1.110 mmol) and 4-methylbenzene-1-sulfonyl chloride (2.327 g, 12.21 mmol) were added. The reaction was stirred at room temperature for 1 hour.Quench the reaction with saturated NH 4 Cl,Extracted with DCM. The organic portion was dried over MgSO 4, filtered and concentrated under reduced pressure to give a residue which was purified by silica gel chromatography eluting with 0-50% ethyl acetate / heptane to give the product (0. 288 g, 1.179 mmol, yield 10.62%).
This compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,(S)-Butane-1,3-diol,24621-61-2,its application will become more common.
