  MIL-101(Cr) has been efficiently utilized for the synthesis of biologically relevant heterocycles such as 1,5-benzodiazepines and spirooxindoles in one-pot. MIL-101(Cr) was prepared via a solvothermal method and characterized by FT-IR, PXRD, SEM, TEM, EDX, and ICP-OES analysis. Thermogravimetric analysis (TGA) described its high thermal stability. Low catalyst loading, easy separation, reusability, and high
