As a common heterocyclic compound, it belongs to thiazolidine compound, name is 1,1-Dioxo-isothiazolidine, and cas is 5908-62-3, its synthesis route is as follows.,5908-62-3
To a mixture of tert-butyl (6S)-3-iodo-6-methyl-6,7-dihydro-4H-pyrazolo[l,5-a]pyrazine- 5-carboxylate (intermediate 1-1, 100 mg, 0.28 mmol), 1,2-thiazolidine 1,1-dioxide (compound la, 50 mg, 0.41 mmol), trans-N,N’-dimethylcyclohexane-l,2-diamine (8 mg, 0.055 mmol) and Cul (10 mg, 0.055 mmol) in DMSO (5 mL) was added K2C03 (114 mg, 0.83 mmol). The reaction mixture was stirred at 100 C for 12 hours, and then concentrated under reduced pressure. The residue was purified by prep-HPLC to give tert-butyl (6S)-3-(l,l-dioxo-l,2-thiazolidin-2-yl)-6- methyl-6,7-dihydro-4H-pyrazolo[l,5-a]pyrazine-5-carboxylate (compound lb, 72 mg) as a yellow solid. MS obsd. (ESI+) [(M+H)+]: 357.
With the complex challenges of chemical substances, we look forward to future research findings about 5908-62-3,belong thiazolidine compound
