With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.147959-19-1,(S)-tert-Butyl 2,2-dimethyl-4-(2-oxoethyl)oxazolidine-3-carboxylate,as a common compound, the synthetic route is as follows.
Ethyl 21b (5.60g) of THF (25.2 ml) suspension, round the leucorrhea the, 2.69 Mn-butyl lithium-hexane solution (7.0 ml) adding an, 30 minutes in the round the leucorrhea stirring section. Reaction solution at a, process obtained in a 4 (S)-tert-butyl 2,2-dimethyl-4 – (2-oxo ethyl) oxazolidine-3-carboxylate (3.06g) THF (3.06 ml) of solution, are added to the round the leucorrhea, adaptation stirring time 14 at room temperature. Adding of cyclohexane to reaction solution at a, know one filtration insoluble, = 2/1-hexanediol THF a washing of section. Filtrate of decompressing concentrated within, obtained residue silica gel chromatography (developing solvent: hexane/acetic acid ethyl) for purifying the, title compound 1.81g is obtained., 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.
