108149-63-9, (R)-tert-Butyl 4-(hydroxymethyl)-2,2-dimethyloxazolidine-3-carboxylate is a oxazolidine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

108149-63-9, Serinol derivative 5 (65 mg, 0.28 mmol) was dissolved in dry DMSO (3 mL) and treated with NaH (5 mg, 60% dispersion in mineral oil, 0.21 mmol) and mesylate 39 (100 mg, 0.14 mmol) was added sequentially. The reaction immediately changed color from nearly colorless to orange red. The reaction was stirred at room temperature for 16 h, and was then quenched by the ice and diluted with ethyl acetate. The two layers were separated and the aqueous layer extracted with ethyl acetate (5 15 mL). The combined organic layers were dried (Na2SO4) and concentrated in vacuo. Purification by flash column chromatography (70:30 petroleum ether/EtOAc) yielded the serinol ether 40 (105 mg, 65%) as colorless oil:

The synthetic route of 108149-63-9 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.108149-63-9,(R)-tert-Butyl 4-(hydroxymethyl)-2,2-dimethyloxazolidine-3-carboxylate,as a common compound, the synthetic route is as follows.

A solution of tert-butyl (4R)-4-(hydroxymethyl)-2-methyl-1,3-oxazolidine-3-carboxylate (9.38 g, 43.17 mmol, 1.00 equiv), Cs2CO3 (28.1 g, 86.24 mmol, 2.00 equiv), and methyl prop-2-enoate (18.6 g, 216.05 mmol, 5.00 equiv) in ACN (80 mL) was stirred for 3 h at room temperature. The solids were filtered out and the residue was concentrated under vacuum to afford 9.92 g of the title compound as a crude yellow oil LCMS (ESI, m/z): 318.18 [M+H]+

General procedure: To a stirred solution of 6 (0.100 g, 0.433 mmol), appropriate substituted phenol (0.649 mmol) and PPh3 (0.182 g,0.693 mmol) in anhydrous toluene (5 mL) was added DIAD(0.14 mL, 0.693 mmol) at 80 C. After 3 h, EtOAc (40 mL)was added to the resulting solution. The organic layer was washed with 0.5 M aqueous NaOH (40 mL) and water (2 X40 mL), dried over Na2SO4, filtered and concentrated. The residue was purified by flash silica gel column chromatography eluting with Hexanes/EtOAc (9:1) or (95:5) to afford compounds 7a-s., 108149-63-9

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.

n-BuLi (2 M in hexane, 1.7 mL, 3.45 mmol, 1.5 eqv.) was added to a stirred suspension of methyltriphenylphosphonium bromide (1.23 g, 3.45 mmol, 1.5 eqv.) in dry THF (10 mL) under argon at 0 C dropwise over 5 min, and the resulting solution was allowed to stir for 20 min at 0 C. A solution of the aldehyde 4 (560 mg, 2.30 mmol) in THF (5 mL) was then added dropwise over 5 min with stirring at the same temperature. After 20 min, the solution was allowed to come to room temperature and stirred for another 4 h. The reaction mixture was quenched by addition of aq NH4Cl solution (3 mL) and then extracted with ethyl acetate (2 x 50 mL). The combined organic extract was washed successively with H2O (40 mL) and brine solution (40 mL) and then dried over MgSO4. It was then filtered, and the filtrate was concentrated under reduced pressure to leave the crude product which was purified by column chromatography over silica gel (EtOAc-PE, 1:19) to give the olefin 1b as a colourless liquid (410 mg, 74 %)., 147959-19-1
