As a common heterocyclic compound, it belongs to thiazines compound, name is 2-(3-Methoxypropyl)-4-oxo-3,4-dihydro-2H-thieno[3,2-e][1,2]thiazine-6-sulfonamide 1,1-dioxide, and cas is 154127-41-0, its synthesis route is as follows.,154127-41-0
Step I: (S)-3,4-Dihydro-4-hydroxy-2-(3-methoxy)propyl-2H-thieno[3,2-e]-1,2-thiazine-6-sulfonamide-1,1-di oxide To a solution of the product of Step H (2.6 g, 7.34 mmol) in THF (30 mL) at -78 C. was added a solution of (+)-beta-chlorodiisopinocampheylborane (11.8 g, 36.7 mmol) in THF (10 mL). The reaction mixture was allowed to warm to -20 C. and kept at this temperature for 4 days. Diethanolamine (4.2 mL, 44 mmol) was added to the reaction mixture and the solution stirred for 30 min, diluted with EtOAc (150 mL), washed with water (2*50 mL) and brine (2*50 mL), dried (MgSO4), and evaporated to a syrup which was purified by column chromatography [silica; CH30 OH/CH2 Cl2 (20:1)] to give 2.4 g (92%) of the desired compound as a colorless foam.
With the complex challenges of chemical substances, we look forward to future research findings about 154127-41-0,belong thiazines compound
