Compound 20: N-(3-(9H-Carbazol-9-yl)-2-hydroxypropyl)isothiazolidine 1,1-dioxide To a stirred solution of 1,3-propanesultam (0.80 g, 6.6 mmol) in anhydrous N,N-dimethylformaide (20 mL) was added sodium hydride (60% in mineral oil, 0.053 g, 1.3 mmol) and the mixture was stirred at room temperature for 1 hour. 9-(Oxiran-2-ylmethyl)-9H-carbazole (1.622 g, 7.3 mmol) was added and the mixture was stirred at 70 C. overnight. After cooling, the reaction was diluted with water and extracted three times with ethyl acetate. The combined organic layers were washed with saturated aqueous sodium chloride, dried (anhydrous sodium sulfate), filtered, and concentrated. The residue was purified by silica gel column chromatography (0-70% ethyl acetate in hexanes) and then recrystallized from ethyl acetate/hexanes to give the pure compound as a white solid (1.6 g, 70%). 1H NMR (300 MHz, CDCl3) delta 8.10 (d, 2H, J=7.5 Hz), 7.48 (d, 4H, J=3.9 Hz), 7.30-7.22 (m, 2H), 4.55-4.35 (m, 3H), 3.42-3.12 (m, 6H), 2.59 (d, 1H, J=3.0 Hz), 2.37 (m, 2H). ESI (m/z): 344.9 (M+H). HPLC analysis: (C18, 10-90% acetonitrile in water+0.1% trifluoroacetic acid over 10 min: retention time, % area at 254 nm): 11.8 min, >98%.
The synthetic route of 5908-62-3 has been constantly updated, and we look forward to future research findings.
