a) (S)-2,2-Dimethyl-4-((R)-3,3,3-trifluoro-2-hydroxy-propyl)-oxazolidine-3-carboxylic acid tert- butyl ester and (S)-2,2-Dimethyl-4-((S)-3,3,3-trifluoro-2-hydroxy-propyl)-oxazolidine-3- carboxylic acid tert-butyl esterTo a cooled, stirred solution of (S)-2,2-Dimethyl-4-(2-oxo-ethyl)-oxazolidine-3-carboxylic acid tert-butyl ester (4.35 g, CAS 147959-19-1) and (trifluoromethyl)trimethylsilane (2.7 ml) in THF (50 ml) at 0 C was added dropwise tetrabutylammonium fluoride solution (1.8 ml, 1 M solution in THF). The reaction mixture was allowed to warm to room temperature and then stirred for a further 30 min. The mixture was then diluted with 2 N aq. HC1 (50 ml) and stirring was continued for a further 30 min. The mixture was extracted twice with ethyl acetate and the combined organic phases were dried over sodium sulfate and concentrated in vacuo. The residue was purified by column chromatography (Si02; gradient: heptane/EtOAc) to give (S)-2,2- dimethyl-4-((S)-3,3,3-trifluoro-2-hydroxy-propyl)-oxazolidine-3-carboxylic acid tert-butyl ester as a colourless viscous oil (1.6 g, 28%, fractions eluting first) and (S)-2,2-dimethyl-4-((R)-3,3,3- trifluoro-2-hydroxy-propyl)-oxazolidine-3-carboxylic acid tert-butyl ester as a colourless viscous oil (2.0 g, 36%, fractions eluting last).
147959-19-1, 147959-19-1 (S)-tert-Butyl 2,2-dimethyl-4-(2-oxoethyl)oxazolidine-3-carboxylate 10586317, aoxazolidine compound, is more and more widely used in various fields.
