The important role of 1,1-Dioxo-isothiazolidine

With the complex challenges of chemical substances, we look forward to future research findings about 1,1-Dioxo-isothiazolidine

Name is 1,1-Dioxo-isothiazolidine, as a common heterocyclic compound, it belongs to thiazolidine compound, and cas is 5908-62-3, its synthesis route is as follows.,5908-62-3

2, 4-Dichloro-5,7-difluoro-3-methylquinoline (800 mg, 3.20 mmol), crude isothiazolidine 1,1-dioxide (390 mg, 3.20 mmol), Pd2(dba)3 (150 mg, 0.16 mmol), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (XantPhos) (280 mg, 0.48 mmol) and cesium carbonate (1.50 g, 4.50 mmol) were slurried in 10.0 mL of dry dioxane along with ~1.0 gram of activated 3 A molecular sieves. The reaction was heated in a microwave reactor at 100 C for 2 h. The reaction was then cooled to rt, diluted with EtOAc and DCM and filtered. The filtrate was concentrated and the residue was purifiied by medium pressure chromatography (silica, 0 to 25% EtOAc : hexanes followed by 0 to 20% EtOAc : DCM) to give 2- (4-chloro-5,7-difluoro-3-methylquinolin-2-yl)isothiazolidine 1,1-dioxide. Mass Spectrum (ESI) m/e = 333.1.

With the complex challenges of chemical substances, we look forward to future research findings about 1,1-Dioxo-isothiazolidine
