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.
(S)-2,2-Dimethyl-4-(2-oxo-ethyl)-oxazolidine-3-carboxylic acid t-butyl ester (2.29 g, 9.44 mmol) was dissolved in dry tetrahydrofuran (25 mL). Then at -78 C., allyl magnesium bromide (1.0M in diethyl ether, 9.9 mL) was added. The mixture was warmed to -15 C. and stirred for 2 h. The mixture was extracted with diethyl ether and aqueous citric acid solution. The organic layer was washed with saturated sodium chloride solution, dried over sodium sulfate and solvents were evaporated to afford (S)-4-(2-hydroxy-pent-4-enyl)-2,2-dimethyl-oxazolidine-3-carboxylic acid tert-butyl ester (2.54 g) as an oil.
The synthetic route of 147959-19-1 has been constantly updated, and we look forward to future research findings.
