A common heterocyclic compound, the thiazolidine compound, name is 1,1-Dioxo-isothiazolidine,cas is 5908-62-3, mainly used in chemical industry, its synthesis route is as follows.
5908-62-3, Step 2-1-(1,1-dioxo-isothiazolidin-2-ylmethyl)-3-benzyl-5-bromo-benzene (8B) A mixture of 8A (5 g, 14.7 mmol), 1,3-propanesultam (3.6 g, 29.7 mmol) and potassium carbonate (4.1 g, 29.7 mmol) in acetonitrile (60 mL) was refluxed overnight. The solvent was removed under reduced pressure. The residue was partitioned between ethyl acetate and brine. The organic phase was dried over sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by flash chromatograph (ethyl acetate/hexanes) to give 8B as a white solid.
As the rapid development of chemical substances, we look forward to future research findings about 5908-62-3
