With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.108149-63-9,(R)-tert-Butyl 4-(hydroxymethyl)-2,2-dimethyloxazolidine-3-carboxylate,as a common compound, the synthetic route is as follows.
To a stirred, cooled (0 C.) solution of (S)-4-hydroxymethyl-2,2-dimethyl-oxazolidine-3-carboxylic acid tert-butyl ester (1.36 g), 2-mercaptobenzothiazole (1.48 g) and triphenylphosphine (2.32 g) in THF (80 ml) under an argon atmosphere was added diethyl azodicarboxylate (4.1 ml; 40% solution in toluene). The mixture (soon turning to a yellow suspension, slowly warming up to r.t.) was stirred for 18 h overnight, then diluted with EtOAc and washed with sat. aq. Na2CO3. The aqueous phase was back extracted with EtOAc. The combined organics were washed with brine, dried over MgSO4, filtered and concentrated. The crude product was purified by column chromatography (SiO2; gradient: cyclohexane->cyclohexane/EtOAc 85:15) to give (R)-4-(benzothiazol-2-ylsulfanyl-methyl)-2,2-dimethyl-oxazolidine-3-carboxylic acid tert-butyl ester (2.1 g) as light yellow viscous oil., 108149-63-9
108149-63-9 (R)-tert-Butyl 4-(hydroxymethyl)-2,2-dimethyloxazolidine-3-carboxylate 11053464, aoxazolidine compound, is more and more widely used in various fields.
