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

(Example 5-1) Under ice cooling, to a dichloromethane solution (20.0 ml) of (S)-1,3-butanediol (519 mg) were added triethylamine (1.04 ml) and tert-butylchlorodiphenylsilane (1.63 ml), followed by stirring at room temperature overnight. The reaction solution was poured into a saturated aqueous ammonium chloride solution, and extracted with ethyl acetate. The organic layer was washed with saturated sodium chloride solution, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The resulting residue was purified by silica gel chromatography to afford (2S)-4-{[tert-butyl(diphenyl)silyl]oxy}butan-2-ol (1.69 g). 1H NMR(400 MHz,CDCl3) delta: 1.05 (9H, s), 1.22 (3H, d, J = 6.3 Hz), 1.58-1.68 (1H, m), 1.69-1.81 (1H, m), 3.31 (1H, d, J = 2.0 Hz), 3.80-3.91 (2H, m), 4.07-4.15 (1H, m), 7.37-7.50 (6H, m), 7.69 (4H, d, J = 6.2 Hz).

This compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,24621-61-2,(S)-Butane-1,3-diol,its application will become more common.
