1438-16-0, An elementary termolecular reaction involves the simultaneous collision of three atoms, molecules, or ions.1438-16-0, name is 3-Aminorhodanine. Here is a downstream synthesis route of the compound 1438-16-0
General procedure: Two indole groups, 1H-indole-3-carbaldehyde (1) and 5-Bromo-1H-indole-3-carbaldehyde (2) (Sigma-Aldrich) were used as the primary core for insertion of the substituents 3-amino-2-thioxo-thiazolidin-4-one, 2-thioxo-thiazolidin-4-one, thiazolidin-2,4-dione and 2-thioxo-imidazolidin-4-one. The substituents were obtained commercially, except thiazolidin-2,4-dione that was synthesized in our laboratory according to the methodology of Brown [69].Prior to this reaction process, the groups 3a, 3b, 3c and 3d were solubilized in ethanol in the presence of morpholine and left stirring for 10 minutes at a temperature of 65 C. After this, indole nucleus (1 and 2) was added to the reaction system to obtain the final derivatives. Change of color was observed in all reactions after addition of indoles and precipitate formation 20min later. The reaction was monitored by thin layer chromatography (TLC) to check product formation and termination of the reaction. In general, the reaction lasted about 1h. As the reaction finished, the products were filtered and subjected to purification by successive washing with ethanol. The purity of the products was verified by 1H NMR, 13C NMR, mass spectroscopy and infrared.
A chemical reaction often occurs in steps, although it may not always be obvious to an observer. Thank you very much for taking the time to read this article. If you are also interested in other aspects of 1438-16-0, you can also browse my other articles.
