Synthesis, Characterization and Catalytic Properties of GO@Fucoidan: A Heterogeneous Bio-Based Catalyst for the Synthesis of α-aminophosphonate Derivatives

In this study, Fucoidan (FU), a fucose-rich sulfated polysaccharide extracted from brown algae Fucus vesiculosus was used for preparation of GO@FU composites. The structural and properties of GO@FU were investigated by EDX, XRD, FT-IR, TGA, SEM, The catalytic activity of GO@FU was studied for the synthesis of α-aminophosphonates through three-component reactions aldehydes/ ketones, amines and nucleophile such as triethyl phosphite. Easy ways of synthesis, high product yield and short reaction time made GO@FU an attractive and efficient heterogeneous biocatalyst for organic chemist.
