If scientists are to successfully address the largest biomedical challenges facing society, our ability to both identify and create functional small molecules with unique properties must improve dramatically. Natural products have long provided great starting points for such investigations given that their structures have evolved over millennia to achieve specific biochemical functions and their synthesis improves our skills. Yet, numerous classes of such structures remain untapped. The most significant of these are oligomeric natural products, compound families created in Nature from a simple building block through deliberately uncontrolled reaction pathways that chemists have never been able to temper in the laboratory. This proposal seeks to provide the innovative synthetic solutions needed to alter this paradigm and finally access these classes of molecules in a controlled manner, thus enabling exploration of their full biochemical potential. Our initial proving ground lies with the resveratrol family of natural products, an abundant class of compounds whose properties in initial screens appear perfect for a rich discovery program given their structural uniqueness and anti-tumor, anti-viral, anti-fungal, anti-oxidant, and anti-aging behavior (many by unknown or unique modes of action). Viewing these targets through the lens of a unique synthetic strategy, we show how the diverse carbogenic complexity of the entire class (along with several non-natural structures) can be assembled from a single, common building block well removed from Nature's starting material through a series of creative complexity-building sequences initiated by the simplest of reagents. These largely unexplored compounds will then be screened thoroughly and deeply in concert with collaborators to elucidate their roles in key biochemical events, especially as relates to human biology.
