Name is 3-Aminorhodanine, as a common heterocyclic compound, it belongs to thiazolidine compound, and cas is 1438-16-0, its synthesis route is as follows.,1438-16-0
B. Preparation of 5-[[3-(1,1-dimethylethyl)-4-hydroxyphenyl]methylene]-3-amino-2-thioxo-4-thiazolidinone The benzaldehyde intermediate from Example 77A (20.0 g; 112.2 mmol), N-aminorhodanine (18.29 g; 123.4 mmol) and sodium acetate (36.8 g; 448.8 mmol) were suspended in 560 ml of acetic acid. The suspension was heated to reflux, stirred at that temperature for 7 hours (at which time a precipitate had formed) and then cooled to room temperature with stirring. The precipitate was recovered by filtration and then washed successively with a 1:1 ethyl acetate/diethyl ether solution then a diethyl ether wash. The recovered precipitate was dried under vacuum at 60 C. for 2 hours to provide 14.5 g of the desired subtitled intermediate. m.p. >225 C.
With the complex challenges of chemical substances, we look forward to future research findings about 3-Aminorhodanine
