1,1-Dioxo-isothiazolidine, cas is 5908-62-3, it is a common heterocyclic compound, the thiazolidine compound, its synthesis route is as follows.,5908-62-3
A microwave vial was charged with (5-{7-chloro-6-fluoro-5-[(S)-oxan-4- yl(phenyl)methyl]-5H-pyrido[3,2-b]indol-3-yl}-4-(2H3)methyl-l-methyl-lH-l,2,3- triazole (30 mg, 0.061 mmol), isothiazolidine 1,1-dioxide (11.1 mg, 0.091 mmol), tripotassium phosphate (18.1 mg, 0.085 mmol), Pd2(dba)3 (2.8 mg, 3.0 muiotatauiotaomicron), 2-di-tert- butylphosphino-3,4,5,6-tetramethyl-2′,4′,6′-triisopropyl-l, -biphenyl (2.9 mg, 6.1 mumol), and dry tert-butanol (0.5 mL). The reaction was heated at 84C overnight. It was diluted with water and extracted with ethyl acetate. The organic layer was concentrated and purified by preparative HPLC (Column: XBridge CI 8, 19 x 200 mm, 5-muiotatauiota particles; Mobile Phase A: 5:95 acetonitrile: water with 10-mM ammonium acetate; Mobile Phase B: 95:5 acetonitrile: water with 10-mM ammonium acetate; Gradient: 15-55% B over 15 min, then a 5-min hold at 100% B; Flow: 20 mL/min) to give 2.1 mg (6%). NMR (500 MHz, DMSO) delta 8.61 (s, 1H), 8.11 (m, 1H), 7.96 (s, 1H), 7.64 (m, 2H), 7.45 (m, 1H), 7.35 (m, 2H), 7.28 (m, 1H), 5.91 (m, 1H), 3.9 (m, 5H), 3.77 (m, 1H), 3.52 (m, 3H), 3.29 (m, 1H), 2.55 9m, 2H), 1.78 (m, 1H), 1.35 (m, 2H), 1.1 (m, 1H); LCMS (M+H) = 578.35
With the rapid development of chemical substances, we look forward to future research findings about 1,1-Dioxo-isothiazolidine
