A great variety of natural and artificial organic compounds makes living easier. Our studies in the laboratory focus on development and construction of organic compounds that are highly controlled in organic reactions. The construction of desired organic compounds is made possible with the clarification of the reaction mechanism. We are working to disclose the reaction mechanism and developing highly controlled enantioselective reactions. Also as an extension, we are working to establish the syntheses of biologically active natural compounds by using our new organic reactions .?@
