A common heterocyclic compound, the thiazolidine compound, name is 1,1-Dioxo-isothiazolidine,cas is 5908-62-3, mainly used in chemical industry, its synthesis route is as follows.
5908-62-3, PREPARATION 1 STR61 A mixture of 4-isopropenyl pyridine (1.79 g) and isothiazolidine-1,1-dioxide (1.81 g) was heated at 130 C. during the addition of “Triton B” (Trade Mark, trimethylbenzylammonium hydroxide) (0.25 g added every hour for four hours; 40% solution in water). After stirring for 16 hours at 130 the mixture was cooled and taken in chloroform (50 cm3) and water (50 cm3). The aqueous phase was extracted with chloroform (3*20 cm3) and the dried (MgSO4) extracts were evaporated to given an oil. Chromatography on silica (“Merck 60. 9385”) eluding with ethyl acetate gave 2-[2-(4-pyridyl)prop-1-yl]isothiazolidine-1,1-dioxide which crystallized from ethyl acetate-hexane as needles, m.p. 90-92 (1.01 g). Analysis %: Found: C,55.0; H,6.8; N,12.0. Calculated for C11 H16 N2 O2 S: C,55.0; H,6.7; N,11.7.
As the rapid development of chemical substances, we look forward to future research findings about 5908-62-3
