As a common heterocyclic compound, it belongs to quinuclidine compound,Quinuclidine-4-carboxylic acid hydrochloride,40117-63-3,Molecular formula: C8H14ClNO331,mainly used in chemical industry, its synthesis route is as follows.,5908-62-3
A sealed tube was charged with 4-iodobenzonitrile (0.50 g, 2.2 mmol), 1 ,2-thiazolidine 1 , 1- dioxide (1.2 equiv.; 0.32 g, 2.6 mmol), dimethylethylenediamine (0.1 equiv., 0.23 mL, 0.22 mmol), cesium fluoride (2.5 equiv., 0.83 g, 5.47 mmol), copper iodide (0.05 equiv., 0.02 g, 0.10 mmol), tetrahydrofuran (4.7 mL) and the reaction contents were stirred at room temperature for 24 hours. The reaction contents were diluted with ethyl acetate and a saturated aqueous ammonium chloride solution. The layers were separated and the organic fraction was washed with water, dried over sodium sulfate, and concentrated under reduced pressure. The corresponding crude yellow oil (449 mg) was taken up in the next step without additional purification or characterization. (0600) NMR (400 MHz, CDCIs) delta ppm: 7.85 (d, 2H), 7.30 (d, 2H), 3.82 (t, 2H), 3.28 (t, 2H), 3.30 (m, 2H).
With the synthetic route has been constantly updated, we look forward to future research findings about 1,1-Dioxo-isothiazolidine,belong thiazolidine compound
