With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.95715-86-9,Methyl (R)-N-Boc-2,2-dimethyloxazolidine-4-carboxylate,as a common compound, the synthetic route is as follows.,95715-86-9
A solution of LiOH (0.046 g, 1.928 mmol) in water (2 mL) was added to a solution of (S)-3-tert-butyl 4-methyl 2,2-dimethyloxazolidine-3,4-dicarboxylate (0.5 g, 1.928 mmol) in THF (6 mL). The resulting mixture was stirred at rt for 48 h, acidified to pH 4 with a 1 N aqueous solution of hydrochloric acid and extracted three times with ethyl acetate. The combined organic phases were dried (MgSO4), filtered and concentrated under vacuum to afford Cap L-25 (0.2 g) as a yellow oil. Used without further purification.1H NMR (400 MHz, DMSO-d6, mixture of rotomers) delta 12.72 (br. s., 1H), 4.33-4.23 (m, 1H), 4.18-4.09 (m, 1H), 3.93 (dt, J=9.0, 3.3 Hz, 1H), 1.56-1.51 (m, 3H), 1.42 (s, 7H), 1.39-1.33 (m, 6H);13C NMR (101 MHz, DMSO-d6, mixture of rotomers) delta 172.32-171.83 (m), 150.7, 93.76-93.42 (m), 79.66-79.01 (m), 65.94-65.54 (m), 58.79-58.57 (m), 28.05-27.74 (m, 3C), 24.93-24.75 (m), 24.16-23.99 (m).
95715-86-9 Methyl (R)-N-Boc-2,2-dimethyloxazolidine-4-carboxylate 688220, aoxazolidine compound, is more and more widely used in various.
