Name is 1,2-Thiazinane 1,1-dioxide, as a common heterocyclic compound, it belongs to thiazines compound, and cas is 37441-50-2, its synthesis route is as follows.
4-Fluoro-2-(l ,1-dioxo-l lambda -[l,2]thiazinan~2-yl)bemonitrile. To a mixture of2,4-difluorobenzonitrile (10.0 g, 72 mmol) and l,l-dioxo-llambda6-[l,2]thiazin-2-ane (8.84 g, 65.4 mmol) in 1:1 tetrahydrofuran/dimethylformamide (40 mL) was added potassium carbonate (9.0 g, 65.4 mmol). The mixture was stirred at 90 0C for 18 h then filtered and concentrated. The residue was purified by flash chromatography (SiO2) eluting with 10%-50% ethyl acetate/hexanes followed by recrystallization from hot ethyl acetate/hexane to give the title compound as white needles (0.537 g, 3% yield). 1H NMR (500 MHz, CD3OD) 5 ppm: 7.70 (IH, dd, J= 8.8, 5.8 Hz), 7.30 (IH, dd, J= 8.8, 2.4 Hz), 7.15-7.12 (IH, m), 3.27 (2H, t, J= 5.3 Hz), 3.33 (2H, t, J= 6.1 Hz), 2.40-2.35 (2H, m), 2.05-2.01 (2H, m). LCMS (M+H) calcd for C11H16N2OF: 255.06; found: 255.19.
37441-50-2, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,37441-50-2 ,1,2-Thiazinane 1,1-dioxide, other downstream synthetic routes, hurry up and to see
