Our group focuses on natural alkaloids possessing complex and unique skeletons as new drug candidates. In order to establish efficient and divergent synthesis of these complex compounds, we are engaged on development of domino-type synthetic transformations and tandem catalysis, which are able to minimize numbers of steps, reagents and operation time. Finally, we are also interesting new hybrid catalysis developed in this research group and willingly utilize the method in our natural product synthesis.
