Heterocyclic Building Blocks-Thiazolidine

A balanced equation for a chemical reaction indicates what is reacting and what is produced, but it reveals nothing about how the reaction actually takes place. The reaction mechanism is the process, or pathway, by which a reaction occurs.5908-62-3, name is 1,1-Dioxo-isothiazolidine. An updated downstream synthesis route of 5908-62-3 as follows., 5908-62-3

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.

General procedure: A solution of 0.002 mol of rhodanine in 5 mL of ethanol and 0.05 mL of 2-aminoethanol were added to a solution of 0.002 mol of aldehyde 1 in 5 mL of ethanol. The mixture was refluxed for 2-3 h and cooled. The precipitate was filtered off and recrystallized.

Any one of these steps may be slow and thus may serve as the rate determining step. In general, however, in the presence of the catalyst, the overall rate of the reaction is faster than it would be if the reactants were in the gas or liquid phase.
