A stirred mixture of [3-(2-Methyl-l,3-dioxolan-2-yl)tricyclo[3.3.1.03’7]non-l-yl] methyl methanesulfonate as obtained in preparation 2 (1.0 g, 2.9 mmol), K2CO3 (1.16 g, 8.7 mmol) and isothiazolidine- 1,1 -dioxide (0.53 g, 4.35 mmol) in DMF (12.0 mL) was heated to 110C for 16 h. The reaction mixture was cooled to room temperature, diluted with water and extracted with EtOAc. The combined organic layer was washed with brine, dried over Na2SO4 and the solvent was removed under reduced pressure. The crude product was purified by column chromatography to obtain 2-{[3-(2-methyl-l,3-dioxolan-2- yl)tricyclo[3.3.1.03’7]non-l-yl] methyljisothiazolidine 1,1-dioxide as a viscous liquid (0.69 g) in 70% yield, m/z (M+l) 342; 1H NMR (CDCl3) 300 MHz delta 4.04-3.92 (m, 4H), 3.30 (t, J= 6.8 Hz, 2H), 3.10 (t, J= 7.4 Hz, 2H), 2.94 (d, J= 14.6 Hz, IH), 2.87 (d, J= 14.6 Hz, IH), 2.40-2.27 (m, 4H), 1.88-1.72 (m, 2H), 1.72-1.55 (m, 4H), 1.55-1.38 (m, 4H), 1.27 (s, 3H).
5908-62-3 1,1-Dioxo-isothiazolidine 642157, athiazolidine compound, is more and more widely used in various.
