Resveratrol-based oligomers are produced combinatorially by plants in response to environmental stress. Snyder and co-workers report that the core structure A can be transformed to every member of the family by simply altering reagents and reaction conditions. Pallidol, quadrangularin, ampelopsins D and F, paucifloral F, and hemsleyanol E were all synthesized by related cationic cyclization cascades.
