Outline of Final Research Achievements |
Asymmetric organocatalysis is one of the most useful methods for a wide variety of enantioselective transformation because of operational simplicity, mild reaction conditions, and the environmentally benign nature of the reaction.1-3 Unlike traditional metal-based catalysts with well-defined metal-ligand coordination, non-covalent interactions, such as hydrogen-bonding interactions, van der Waals interactions, and electrostatic interactions, play a central role in controlling the stereochemical outcome of the organocatalysts. A conformational search program for finding low-energy conformations of large noncovalent complexes has been developed. Quantitatively reliable semiempirical quantum mechanical PM6-DH+ method, which is able to accurately describe noncovalent interactions at a low computational cost, was employed in contrast to conventional conformational search programs in which molecular mechanical methods are usually adopted.
