target setting: The merging of natural product and non‐natural product based hierarchical scaffold trees annotated with bioactivity (see schematic illustration) together with brachiation along structural lines of biological relevance provides a novel strategy for the prospective identification of protein targets for compound collections inspired by natural product structures.

Two steps is the rule: A concise synthesis of versatile α′‐methoxy‐γ‐pyrones (see scheme) is described that uses an innovative desymmetrization of α,α′‐dimethoxy‐γ‐pyrone, relying upon conjugate addition of nucleophiles. This new strategy is applied to the preparation of α‐methyl‐ and α‐carboxaldehyde‐α′‐methoxy‐γ‐pyrones and to a short synthesis of verticipyrone.
