Ovalbumin: as a nano-biocatalyst in three-component synthesis of chromene derivatives

چکیده مقاله

Nanoovalbumin is a biodegradable phosphoglyco protein with molecular weight of 44.5 kDa containing 385 residues of amino acids. Nano-ovalbumin can be used as a non-toxic heterogeneous and eco-friendly catalyst for promotion of organic compounds. In this research, nanoovalbumin, Which was extracted directly from egg white, was used for the synthesis of dihydropyrano[3,2-c]chromene derivatives. Products were identify by spectroscopic methods. Such as FT-IR, 1H NMR, and etc.
