Flexible application of 3,4-Dihydro-2H-benzo[b][1,4]thiazine in synthetic route

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand 3080-99-7 reaction routes.

An elementary termolecular reaction involves the simultaneous collision of three atoms, 3080-99-7, molecules, or ions. Here is a downstream synthesis route of the compound 3080-99-7, name is :3,4-Dihydro-2H-benzo[b][1,4]thiazine

In a manner similar to the method described in Example 1-1, using 3,4-dihydro-2H-benzo[1,4]thiazine in place of 1,2,3,4-tetrahydroquinoline, 239 mg (yield: 63%) of the captioned compound was obtained.1H-NMR (ppm) (300 MHz, CDCl3) 6.98 (1H, dd, J = 1.8, 7.9 Hz), 6.86 (1H, ddd, J = 1.8, 7.3, 8.5 Hz), 6.78 (1H, d, J = 8.2 Hz), 6.69-6.65 (2H, m), 6.61-6.5 (1H, ddd, J = 1.2, 7.6, 8.5 Hz), 4.61 (1H, d, J = 8.2 Hz), 3.85 (3H, s), 3.60-3.51 (3H, m), 3.14-2.96 (4H, m), 2.55-2.50 (1H, m), 2.41 (3H, s), 2.38-2.32 (1H, m), 2.23-2.12 (2H, m), 1.91-1.47 (5H, m), 1.12-1.00 (1H, m) IR (cm-1) (KBr) 2924, 1735, 1606, 1584, 1483, 1438, 1373, 1338, 1275, 1257, 1176, 1148, 1112, 1079, 1047, 1006, 937, 907, 891, 854, 793, 744
