Our group focuses on the development of new transition metal-catalyzed reactions, and on conducting integrated research of plant science and chemistry with emphasis on sustainable resource science. In particular, we aim at developing methodologies for manipulation and/or modulation of structures and functions of organic molecules by catalytic oxidation reactions utilizing molecular oxygen, which will contribute to the effective utilization of carbon- and metal-based resources. In addition, investigation on the transformations of readily accessible natural organic molecules into valuable materials based on fine synthetic organic chemistry, as well as on the effective utilization of materials synthesized by newly developed reactions or from secondary metabolites of plants are of interest. In particular, we are studying various aspects of secondary metabolites of plants, whose effects on plants and animals have not been well clarified. Furthermore, this group will also contribute to enhance the collaboration between plant/microbiology research and chemical research activities inside CSRS.
