| Outline of Research at the Start |
In this project, a novel catalytic asymmetric synthetic method for the chromone lactone compounds will be established. The intriguing enantioface-differentiation mechanism for the unexpected and unprecedented anti-selectivity will be clarified. (+)-Lachnone C, epi-(+)-microdiplodiasone, (+)-gonytolides C&G and their simplified analogues will be synthesized and subjected to in vitro screening in order to identify the potential antibacterial and/or anticancer lead compounds
|
| Outline of Final Research Achievements |
This study achieved the development of a new synthetic method for chromanone lactones. The method is applicable to chromones with different substitution groups and has yielded natural product analogs with excellent diastereo- and enantioselectivity. Additionally, successful syntheses of ent-blennolide B and secalonic acid A were also achieved.
|
| Academic Significance and Societal Importance of the Research Achievements |
The method developed in this study could be used for the synthesis of biologically important natural products in an effective manner which may accelerate drug discovery based on natural products.
