With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.114525-81-4,(R)-4-(tert-Butoxycarbonyl)thiomorpholine-3-carboxylic acid,as a common compound, the synthetic route is as follows.

To a 25mL round bottom flask, Intermediate 7 (540 mg, 1.45 mmol), Intermediate 9 (359 mg, 1.45 mmol), EDCI (418 mg, 2.18 mmol), HOBt (294 mg, 2.18 mmol), DIEA (374 mg, 2.9 mmol) and tetrahydrofuran (9 mL) were added, and stirred at room temperature overnight. Thereafter, the reaction product was subjected to vacuum distillation for removal of solvent, dissolved with water, and extracted 3 times with ethyl acetate. The extracts were combined, washed 3 times with saturated brine, concentrated, and separated through a silica gel column (eluent: petroleum ether/ethyl acetate), to give 688 mg of a white foamy solid product, yield 78.8%. [0081] 1H-NMR (400 MHz, CDCl3) delta ppm: 7.42 (1H, d, J = 1.12 Hz), 7.27 (2H, m), 5.75 (1H, s), 5.19 (1H, s), 4.58 (2H, s), 3.95-3.44(10H, brm), 3.12 (1H, m), 2.82 (2H, m), 2.43 (2H, m), 1.92 (9H, s); EI-MS (m/z): 601.1 [M+H]+.

114525-81-4 (R)-4-(tert-Butoxycarbonyl)thiomorpholine-3-carboxylic acid 2755966, aThiomorpholine compound, is more and more widely used in various.

114525-81-4, (R)-4-(tert-Butoxycarbonyl)thiomorpholine-3-carboxylic acid is a Thiomorpholine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

Referring to Scheme 5-2, a mixture of compound 17 (667 mg, 2.4 mmol), (R)-N-Boc-thiomorpholine-3-carboxylic acid (594 mg, 2.4 mmol) and Et3N (486 mg, 4.8 mmol) in EtOAc (20 mL) was stirred at rt for 2h. Subsequently, the reaction mixture was concentrated and the residue was dried in vacuo to give crude compound 19, which was used for the next step without further purification. LC-MS (ESI): m/z 466.0 (M+Na)+.

As the paragraph descriping shows that 114525-81-4 is playing an increasingly important role.

(Scheme F, F-3: where RF-1 and RF-2 are the same and equal to proton, RF-3 is t-butyl, R5 is 4-[(2,6-dichlorobenzoyl)amino]phenyl and stereochemistry is (R,S)). [C00180] [00425] To a cooled (0-5 C.) solution of Boc-L-thiomorpholine-3-carboxylic acid (Scheme F, F-1: where RF-1 and RF-2 are the same and equal to proton and stereochemistry is (R)) (1.34 g, 5.4 mmol) in methylene chloride (20 mL) was added HOBt (800 mg, 5.94 mmol), DMAP (140 mg, EDC (1.14 g, 5.94 mmol) and triethylamine (2.7 mL, 19.4 mmol). After 10 min, F-2 (Scheme F where RF-1 and RF-2 are the same and equal to proton, RF-3 is t-butyl, R5 is 4-[(2,6-dichlorobenzoyl)amino]phenyl and stereochemistry is (S)) (2.02 g, 4.94 mmol) was added, the reaction allowed to warm to ambient temperature and stirred for 24 h. Volatiles were removed in vacuo and the residue partitioned between methylene chloride and 2.5% aqueous HCl. The organic layer was separated and washed with sat. aqueous NaHCO3, dried and concentrated in vacuo. Purification of the residue by flash chromatography using methylene chloride/ethyl acetate (5%) as eluant afforded the title compound (1.64 g): IR (mull) 1730, 1687, 1667, 1606, 1538, 1515, 1431, 1412, 1395, 1320, 1294, 1258, 1250, 1194, 1158 cm-1; 1H NMR (300 MHz, CDCl3) delta 1.44 (9H), 1.46 (9H), 2.35 (1H), 2.67 (3H), 3.22 (3H), 4.25 (1H), 4.73 (1H), 4.97 (1H), 6.52 (1H), 7.29 (5H), 7.53 (3H); MS (FAB) m/z (rel. intensity) 638 (M+H, 2), Anal.
