5908-62-3, 1,1-Dioxo-isothiazolidine is a thiazolidine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Intermediate 5 (0.109 g, 0.114 mmol) was combined with isothiazolidine 1,1-dioxide (0.139 g, 1.145 mmol) in anhydrous acetonitrile (1.1 mE). para-Toluenesulfonic acid monohydrate (0.0022 g, 0.011 mmol) was added. The reaction was stirred at room temperature for two hours. 10503] The reaction was diluted with saturated aqueous NaHCO3. The mixture was extracted several times with EtOAc. The organic extracts were combined, dried over Na2SO, decanted and concentrated to give a yellow tar crude product.10504] The crude product was purified by silica gel flash column chromatography (0-40% acetone-heptane, gradient elution, 24 g silica column, TEC in 40% acetone-heptane, visualize under UV) to give Example 17 (0.053 g, 0.046 mmol, 40.0% yield) as a white solid.Example 1710505] ESIMS [M+H] 1041.8, [M-H] 1039.8.10506] HRMS: calculated for C54H84N6012SNa-1063.5765.
