3-Aminorhodanine, cas is 1438-16-0, it is a common heterocyclic compound, the thiazolidine compound, its synthesis route is as follows.
EXAMPLE 12 5-[4,6-Bis(1,1-dimethylethyl)-5-hydroxy-2-pyrimidinyl]methylene]-3-amino-2-thioxo-4-thiazolidinone A mixture of 4,6-bis(1,1-dimethylethyl)-5-hydroxy-2-pyrimidine carboxaldehyde (1.00 g, 4.23 mmol), sodium acetate (1.36 g, 16.6 mmol), and 3-aminorhodanine (0.63 g, 4.3 mmol) in glacial acetic acid (15 mL), under nitrogen atmosphere, is warmed to reflux and refluxed 7 hours. This mixture is then cooled to room temperature and stirred 16 hours. After stirring, the reaction mixture is diluted with a 1:2 mixture of ethanol and water and extracted with ethyl acetate. The combined organic extracts are washed with water, aqueous 0.2N hydrochloric acid solution, and brine. The organic phase is dried over magnesium sulfate, concentrated, and purified by flash chromatography (SiO2, 20% ethyl acetate/hexane) followed by recrystallization from methanol and water to give 0.42 g (27%) of the title compound, mp 194-196 C., 1438-16-0
With the rapid development of chemical substances, we look forward to future research findings about 3-Aminorhodanine
