Fun Route: New Discovery of 24621-61-2

A chemical reaction often occurs in steps, although it may not always be obvious to an observer. Thank you very much for taking the time to read this article. If you are also interested in other aspects of (S)-Butane-1,3-diol, CAS: 24621-61-2, you can also browse my other articles.

Rate laws may be derived directly from the chemical equations for elementary reactions. This is not the case, however, for ordinary chemical reactions.24621-61-2, name is (S)-Butane-1,3-diol, 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).
