Total synthesis of diverse carbogenic complexity within the resveratrol class from a common building block.

Although biomimetic approaches have proven capable of converting resveratrol (1) concurrently into many of the more complex oligomers produced by plants throughout the world (such as 2-10), methods to access single members of the family have proven far more difficult to identify. Herein is described a strategy-level solution based on the use of a common building block, one distinct from Nature's starting material, that can participate in a variety of highly selective, reagent-controlled reaction cascades. These endeavors have led to the controlled synthesis of 25 natural products and analogues, molecules whose architectures encompass nearly all the carbogenic diversity of the resveratrol family.
