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

Abstract Titanium silicate (TS-1) zeolite heterogeneous catalyst is synthesized by the hydrothermally discontinuous method and is characterized by using XRD, SEM, TEM, and NH3–TPD techniques. The catalytic activity of the TS-1 type zeolite was tested for one-pot solvent-free synthesis of 1,3-thiazolidine-4-ones. The present technique illustrates many benefits, including eco-friendly reaction conditions
ABSTRACT A one-pot three-component reaction for the synthesis of 4-thiazolidinone derivatives has been established by reacting readily available and inexpensive starting materials of amines, aldehydes and thioglycolic acid using Y(OTf)3 (5 mol%) as catalyst in tetrahydrofuran. This method is very efficient due to low catalyst loading and mild reaction conditions and provides an efficient and promising
