| Outline of Final Research Achievements |
We have investigated that development of oxidative kinetic resolution of tetralones by using organocatalyst for providing an optically active tetralones. In this project, oxidative kinetic resolution of tetralone-derived beta-ketoester based on enantioselective alpha-hydroxylation by using guanidine-bisurea bifunctional organocatalyst was developed, and the reaction was applied to synthetic study of rishirilide B. As a result, we have achieved to synthesize both enantiomers of natural product, and the absolute configuration of natural (+)-rishirilide B was revised by chiral HPCL analysis.
