37441-50-2, 1,2-Thiazinane 1,1-dioxide is a thiazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A flask was charged under nitrogen with 1,1-dimethylethyl 3-bromo-5-iodobenzoate (D7)(1 g, 2.6 mmol, 1 equiv), Cs2CO3 (1.26 g, 3.9 mmol, 1.5 equiv),tris(dibenzylideneacetone)dipalladium(0) (12 mg, 0.013 mmol, 0.005 equiv), Xantphos (22 mg, 0.038 mmol, 0.015 equiv) and toluene (20 ml). Tetrahydro-2H-1,2-thiazine 1,1-dioxide (D6) (350 mg, 2.9 mmol, 1.1 equiv) was then added and the resulting mixturewas stirred at 100C for 16 h then cooled to room temperature and diluted with AcOEt.The organic phase was washed with saturated aqueous NaHCO3 solution, dried overMgSO4 and concentrated in vacua. The residue was triturated with Et2O to give 1,1-dimethylethyl 3-bromo-5-(1,1-dioxidotetrahydro-2/-/-1,2-thiazin-2-yl)benzoate (D8) (590mg, 58%) as a white solid.
37441-50-2 1,2-Thiazinane 1,1-dioxide 303508, athiazines compound, is more and more widely used in various.
