In an idealistic setting, it can be imagined that if every CH bond on an organic molecule could be selectively functionalized, the fields of chemical synthesis and drug discovery would be forever revolutionized. With the purpose of investigating the practicality of this idealistic scenario, our group has endeavored to unlock the potential of nature's CH bonds by developing palladium-catalyzed, site selective CH insertions that can be incorporated into both known and new catalytic cycles. To this end, we have developed a number of catalytic transformations that not only provide rapid diversification of simple starting materials and natural products through CH functionalization, but streamline the synthesis of a variety of natural products with biological activity and expand upon methods to access highly valuable enantiopure materials.
