With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.5908-62-3,1,1-Dioxo-isothiazolidine,as a common compound, the synthetic route is as follows.
To a mixture of Intermediate 1 (1 equiv.) and isothiazo lidine 1,1-dioxide (1.2 equiv.) in 1 ,4-dioxane was added cesium carbonate (1.5 equiv.). The reaction was heated to 100 C for 16 h, after which the reaction was diluted with water, and extracted with ethyl acetate. The combined organic layers were dried over sodium sulfate, filtered, and concentrated in vacuo. The crude material was purified via silica gel chromatography utilizing a 3-10% methanol in dichloromethane gradient to deliver the desired compound, Compound 1-503 (71.3 mg, 73% yield) as an off- white solid.1H-NMR (500 MHz, CDC13) oe 8.57 (d, 1 H), 8.47 (d, 1 H), 7.36 (s, 1 H), 7.20-7.25 (m, 1 H),7.03-7.07 (m, 1 H), 6.96-7.01 (m, 1 H), 6.84-6.88 (m, 1 H), 6.61 (m, 1 H), 5.99 (s, 2 H), 4.27 (t, 2 H), 3.44 (t, 2 H), 2.66 (t, 2 H).
The synthetic route of 5908-62-3 has been constantly updated, and we look forward to future research findings.
