Synthesis and BSA binding study of the Cu(II) complex and applications of it to enhance catalytic activity for C(Sp2)-H bond functionalization and for the synthesis of polyhydroquinolines

Among the various copper-catalyzed coupling reactions, C–S and C–N bond-forming reactions have carried off plentiful recognition due to their demand in the synthesis of molecules having biological and pharmaceutical impact. Organo-copper complex has an incontestable supremacy over the other catalytic complex due to its low cost and the use of readily accessible and stable ligands. As a consequence and in continuation of our explorative studies in this direction, an efficient and novel organo-copper complex has been synthesized and characterized by spectroscopic (NMR, FT-IR) and single crystal X-ray diffraction (XRD) methods. The synthesized stable metal complex has fascinating physical, chemical, biological and catalytic properties. In the chemical exploration refer to protein-metal interactions; we have often used Bovine Serum Albumin (BSA) protein. The synthesized copper complex has the potential to form coordinate bonds with functional groups present in BSA, together with amino acid residues and the protein backbone. The binding of metal complexes to BSA has outstanding imputation in medicinal chemistry. For enhancement of the catalytic activity of the organo-copper complex, we have evaluated it in carbon-hetero bond formation reactions where it proffered an influential tool for the establishment of C–S and C–N bonds.
