Grant Details
Description
DESCRIPTION (provided by applicant): The long term objectives of this grant application are focused on the total syntheses of natural products with promising biological profiles and the development of new synthetic methods. The development of new synthetic methods that are simple, efficient and general in scope continues to be an essential scientific pursuit. Such methods serve many needs of basic science and enable the development of new pharmaceuticals and other essential chemical structures. Natural products have greatly impacted public health over the last sixty years by serving as the source or lead structures for new drugs. A large percentage of currently used antibiotics and cancer therapeutics are natural products or derivatives of natural products. This proposal describes efforts to design and execute efficient synthetic blueprints towards several natural product diterpenoids with unique and promising biological modes of action. These synthetic blueprints will provide access to collections of unique natural product hybrid structures. These otherwise inaccessible compound collections will help unravel and shed light on the biological significance each one of these natural product structural features play, which is expected to be critical for further advancement and applications. The efficiency of the proposed synthetic routes detailed herein are enabled by strategic use of an underdeveloped oxidative dearomatization protocol. The mechanism and scope of this powerful oxidative dearomatization protocol will be rigorously evaluated in order to enable development of asymmetric variants as well as to provide a blueprint for future applications. The reactivity of the synthons generated using this method will be established during the grant period. PUBLIC HEALTH RELEVANCE: The goal of this grant application is to complete total syntheses of three different classes of bicyclic natural products. In all proposed synthetic approaches a perfectly suited dearomatization protocol, which we plan to study and advance during the grant period, serves as the cornerstone. Our efficient synthetic routes will be used to create unique natural product hybrid collections that will prove invaluable in decoding these natural products molecular mechanisms, which in turn should help advance their development. The new synthetic method proposed will benefit chemists both in academia and the pharmaceutical industry thus directly or indirectly impacting the discovery, study, development and production of new drugs.
