AbstractA mild and efficient protocol for the synthesis of 2‐amino‐5‐arylidene‐1,3‐thiazol‐4(5H)‐ones is reported by three component reaction of aldehydes, rhodanine and secondary amines in the presence of magnesium oxide nanoparticles as heterogeneous nanocatalyst in good yields and short reaction times.

γ-Aminobutyric acid hydrochloride immobilized on superparamagnetic γ-Fe2O3@SiO2 nanoparticles as a novel heterogeneous nanocatalyst was prepared for the first times. It was characterized by several techniques such as XRD, FT-IR, VSM, FE-SEM, EDS, and TGA analysis. The heterogeneous nanocatalyst was used for a convenient, mild, and one-potefficientthree-componentpreparation of 2-amino-5-alkylidene-thiazol-4-one
