With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.99395-88-7,(S)-4-Phenyloxazolidin-2-one,as a common compound, the synthetic route is as follows.
4S)-3-{[(4-Methoxybenzyl)thio]acetyl}-4-phenyI-l,3-oxazolidin-2-one; [(4-Methoxybenzyl)thio] acetic acid (1.3 g, 6.1 mmol) was dissolved in dry CH2Cl2 (40 ml) and given O0C. N,N’-Dicyclohexylcarbodiimide (DCC, 6.1 g, 6.1 mmol) and 4- (dimethylamino)pyridine (DMAP, 1.6 g, 12.9 mmol) were added and the mixture was stirred for 30 minutes. (S)-(+)-4-Phenyl-2-oxazolidinone (1,0 g, 6.1 mol) was added and the mixture was stirred at room temperature for 24 hours. The mixture was filtrated, concentrated under reduced pressure and purified by flash-chromatography (Hex : EtOAc 8:2 then 1:1). This afforded the title compound.1H-NMR (CDCl3, 200 MHz): delta 3.46-3.59 (m, 3H), 3.74-3.76 (m, 4Hj, 4.23-4.28 (m, IH), 4.68 (t, J = 8.8 Hz, IH), 5.38-5-42 (m, IH), 6.78 (d, J = 8.6 Hz, 2H), 7.14 (d, / = 8.6 Hz, 2H), 7.32-7.40 (m, 5H)., 99395-88-7
99395-88-7 (S)-4-Phenyloxazolidin-2-one 730424, aoxazolidine compound, is more and more widely used in various fields.
