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.76176-87-9, Thiomorpholine-1-oxide hydrochloride it is a common compound, a new synthetic route is introduced below., 76176-87-9
To Intermediate 6 (2.77 g, 8.7 mmol, 1 eq), 1AI-thiomorpholin-1-one hydrochloride (1.62 g, 10.4 mmol, 1.2 eq) and NaOAc (853 mg, 10.4 mmol, 1.2eq) in anhydrous CH2CI2 (200 mL) was added NaBH(OAc)3 (2.94 g, 13.9 mmol,1 .6 eq). The reaction mixture was stirred at rt overnight. Then, it was partitioned with 1 N NaOH (50 mL) and H20 (50 mL), and extracted with CH2CI2 (3 x 20 mL). The combined organic extracts were dried over MgSO4, filtered and the solvent was removed in vacuo. Purification by silica gel column chromatography withEtOAc/MeOH (1:0-9:1), then CH2CI2/MeOH (1:0-4:1) yielded Intermediate 8 asa white solid (2.48 g, 68%).1H NMR (300MHz, DMSO-d5) oH. 8.62 (d, J=2.lHz, 1H), 8.51 (d, J=2.3Hz, 1H),4.00 (m, 4H), 3.74-3.84 (m, 6H), 2.83-3.00 (m, 4H), 2.61-2.81 (m, 4H).MS (ESj 422.1 (100%, [M+H]j.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 76176-87-9, and friends who are interested can also refer to it.
