3080-99-7, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 3,4-Dihydro-2H-benzo[b][1,4]thiazine, cas is 3080-99-7,the thiazines compound, it is a common compound, a new synthetic route is introduced below.
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
The chemical industry reduces the impact on the environment during synthesis,3080-99-7,3,4-Dihydro-2H-benzo[b][1,4]thiazine,I believe this compound will play a more active role in future production and life.
