Brief Introduction


The field of total synthesis of natural products has shown dramatic progress over the last century. Through the collective effort of the synthetic community, complex targets have been synthesized using inventive solutions, and those solutions have formed the basis for the development of new drugs and materials. With increasing expectations imposed on synthetic organic chemists, the role of total synthesis (i) as a driving force for the discovery of novel and efficient reactions, (ii) as a tool to enhance the understanding of biosynthetic machineries, and (iii) as a means for generating chemicals of extraordinary biological significance in substantial quantities will continue to grow.

With these goals in mind, our group is interested in the synthesis of complex natural products. Our targets would serve as an arena for the exploration of intrinsic reactivities of the molecules and the discovery of new transformations for a novel type of bond formation. Our pursuit of convergent and flexible synthetic approaches should enable access to not only a single target but various natural products with structural and biosynthetic relevance, or unnatural products with higher biological potency.

Research topics

Natural products total synthesis
Methods development for novel type of bond formation
Development of chemical tools for biological studies
