Laboratory for Computational and Experimental CatalysisDepartment of Chemistry College of Science Rikkyo UniversityThe increasing importance of enantiopure molecules in pharmaceutical and medicinal chemistry has stimulated the development of new and efficient asymmetric calalyst. An exhaustive screening of catalysts is generally required to identify the best asymmetric catalyst. Theoretical calculation enables the visualization of appropriate catalysts to elucidate their electronic and structural properies. Recent development of computational methods, software, and hardware enables accurate calculations and allows not only explanation but also prediction of stereoselectivity even in large molecular system. Therefore, theoretical calculation play an increasingly important role in the design of asymetric catalyst. In our laboratory, well-designed asymmetric catalysts are developed with aid of theoretical calculations.
