3-Aminorhodanine, cas is 1438-16-0, it is a common heterocyclic compound, the thiazolidine compound, its synthesis route is as follows.,1438-16-0

General procedure: A mixture of aminorhodanine (1 mmol), isatin (1 mmol) and 5 muL of acetic acid in 2mL of distilled ethanol was placed in a cylindrical quartz reactor (Phi = 4 cm). The reactor was introducedinto a monomode microwave (Anton Paar) apparatus, for 5 min at100 C and 50 Watts. The crude reaction mixture was allowed tocool down at room temperature and ethanol (10 mL) or mixture of H2O/EtOH (10 mL) was directly added in the cylindrical quartzreactor. The resulting precipitated product was filtered off and waspurified by recrystallization from ethanol if necessary.

With the rapid development of chemical substances, we look forward to future research findings about 3-Aminorhodanine
