A visible-light-induced, one-pot mild and efficient, multicomponent-tandem synthesis of diversified 1,3-thiazolidin-4-ones under catalyst and solvent-free conditions is reported. Here, visible-light, an ideal source of energy, has been used as photochemical activator to generate CN and CS bonds under radical mechanistic pathway from aromatic amines, aldehydes and thioglycolic acid. The reported methodology
An efficient three-component synthesis of 1,3-thiazolidin-4-ones is described by one-pot condensation of aldehydes, aniline and thioglycolic acid with nano-CdZr4(PO4)6 as a robust heterogeneouscatalyst under ultrasonic irradiation. Use of simple and readily available starting materials, experimental simplicity, applying the sonochemical methodology as an efficient method and innocuous means of activation
CoFe<sub>2</sub>O<sub>4</sub>@SiO<sub>2</sub>/PrNH<sub>2</sub> nanoparticles as highly efficient and magnetically recoverable catalyst for the synthesis of 1,3-thiazolidin-4-ones
An efficient three-component synthesis of 1,3-thiazolidin-4-ones is described by one-pot condensation of aldehydes, aromatic amine and thioglycolic acid with nano-CoFe2O4@SiO2/PrNH2 as a robust heterogeneous catalyst. The significant advantages of this protocol are the use of magnetically recoverable catalyst, high to excellent product yields, operational simplicity and the use of CoFe2O4@SiO2/PrNH2 nanoparticles as an environment-friendly catalyst.
