Chemistry

Catecholic/polyphenolic moieties are involved in a variety of molecular interactions that mediate the adhesion, cohesion, coloring, and other properties of organic materials in nature. We design novel biomaterials by mimicking the unique chemical structures of these catecholic/polyphenolic materials to address the current unmet needs in biomedical engineering.

Most of drugs, including Remdesivir® as a potential candidate for COVID-19, have chiral carbon-centers and Thalidomide-scandal had brought the importance of stereoselective synthesis of drugs. In this sense, we pursue the development of practical and efficient asymmetric reactions to apply for the lab-scale or bulk-scale synthesis of chiral drugs. To realize that, we focus on 1) the design and the synthesis of novel chiral catalysts, 2) the development of practical reagents, and 3) the development of novel methodology for C-C, C-O, C-N, or C-B bond formations.
