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, Step 3: Preparation of (S)-3 -(tert-butoxycarbonyl)-2,2-dimethyloxazolidine-4- carboxylic acid (Intermediate 4) To a solution of (5)-3-tert-butyl-4-methyl 2,2-dimethyloxazolidine-3,4- dicarboxylate (6.75 g, 26.0 mmol) in THF (80 mL) and water (40 mL) was added lithium hydroxide hydrate (1.20 g, 28.6 mmol) at room temperature. The reaction mixture was. stirred for 12 hours at room temperature. After evaporation of volatile solvents, the residue was diluted with EtOAc, neutralized with 2 N aq. HC1, washed with brine, dried over Na2SO4, filtered and concentrated in vacuo to obtain the title compound (6.32 g, 99%), which was used for the next reaction without further purification.?H-NMR (400 MHz, CDC13): (two sets of rotamers) 4.40-4.5 1 (m, 1H),4.17-4.28 (m, 1H), 4.11-4.15 (m, 1H), 1.62 and 1.67 (s and s, 3H), 1.51 and 1.54 (s and s, 3H), 1.43 and 1.51 (s and s, 9H).
The synthetic route of 95715-86-9 has been constantly updated, and we look forward to future research findings.
