Research theme

Asymmetric organocatalysis

Asymmetric synthesis of biologically active compounds using organocatalysts are attracting more and more attention in these days because of their environmentally benign nature. Our current research topic includes developing novel asymmetric reactions using organocatalysts, as well as analyzing these reactions using quantum chemical calculations and developing a prediction system using machine learning.

Catalysis of cellulose nanofibers

Proline, one of the natural amino acids, functions as an organocatalyst, promoting important bond-forming reactions such as the aldol reaction. Although proline is an inexpensive and harmless, it suffered from poor activity and instability. We recently have discovered that cellulose nanofibers can promote proline catalysis and improve selectivity. We are now conducting research to elucidate the mechanism of this interesting phenomenon and to apply it to various catalytic reactions.

Pickering emulsion catalysis

Amphiphilic nanoparticles are known to exhibit emulsifying properties as surfactants. We are focusing on this phenomenon and developing new production processes for pharmaceutical compounds by integrating organocatalysis and enzymatic reaction technologies.
