Application of 2,3-Dihydrobenzo[b][1,4]dioxine-5-carboxylic acid

While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant. 114525-81-4, we look forward to future research findings about .

Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 114525-81-4, name is (R)-4-(tert-Butoxycarbonyl)thiomorpholine-3-carboxylic acid. This compound has unique chemical properties. The synthetic route is as follows. 114525-81-4

To a 25 mL 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%.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
