Our Research Goal and Topics

Catalytic transformation of aliphatic and unsaturated systems into value-added structures

Our research goal is to develop synthetic methods based on the // understanding of reactivities of catalytic manifolds.
We investigate metal catalyzed inert bond activation, annulation, cycloaddition and hydrofunctionalization reactions.
