As a common heterocyclic compound, it belong Thiomorpholine compound,(R)-4-(tert-Butoxycarbonyl)thiomorpholine-3-carboxylic acid,114525-81-4,Molecular formula: C10H17NO4S,mainly used in chemical industry, its synthesis route is as follows.
To a 100 mL round bottom flask, Intermediate 15 (1.28 g, 3.28 mmol), Intermediate 9 (0.81 g, 3.28 mmol), EDCI (0.94 g, 4.92 mmol), HOBt (0.66 g, 4.92 mmol), DIEA (0.85 g, 6.56 mmol) and tetrahydrofuran (40 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: ethyl acetate/methanol/ammonia), to give 1.63 g of a white foamy solid product, yield 80.5%.1H-NMR (400 MHz, CDCl3) delta ppm: 8.77 (1H, m), 8.02 (1H, m), 7.43 (1H, m), 7.31 (1H, m), 7.20 (1H, m), 7.05 (1H, m), 6.56 (1H, m), 4.85 (2H, d, J=5.2 Hz), 4.02-3.44 (10H, brm), 3.13 (1H, m), 2.83 (2H, m), 2.44 (2H, m), 2.02 (9H, s); EI-MS (m/z): 618.2 [M+H]+.
With the synthetic route has been constantly updated, we look forward to future research findings about (R)-4-(tert-Butoxycarbonyl)thiomorpholine-3-carboxylic acid,belong Thiomorpholine compound
