As a common heterocyclic compound, it belongs to quinuclidine compound,Quinuclidine-4-carboxylic acid hydrochloride,40117-63-3,Molecular formula: C8H14ClNO184,mainly used in chemical industry, its synthesis route is as follows.,5908-62-3
A 40 mL scintillation vial was charged with 1 ,1-dloxo-isothiazolidine (115 mg, 0.949 mmol) and OMF (3 mL). The reaction mixture was cooled to 00C and sodium hydride (95 mg, 2.373 mmol) was added. The reaction was left to stir at room temperature for 20 min foliowed by the addition of 3-bromo~5-(chloromethyl)pyridine hydrochloride (277 mg, 1.139 mmol). The reaction was stirred at room temperature for 3 h, then quenched with water and extracted with ethyi acetate. The organic layer was washed with water twice, dried over sodium sulfate and concentrated in vacuo. The crude was purified by silica gei flash chromatography using heptane-ethyl acetate (6(MO, v/v) to afford 3-bromo-5-(1,1- dioxo-isothiazolidin-2?ylmethyl)?pyridine as a colorless oil. MS (ESI) m/z 292.9 <;M+H)+
With the complex challenges of chemical substances, we look forward to future research findings about 1,1-Dioxo-isothiazolidine,belong thiazolidine compound
