A diastereoselective method of preparing benzofuran-based 4,5-spirocycles via metal catalyzed alkenylation is described. The method can be used to provide compounds containing the benzofuranone-4,5-spirocyclic motif of the phainanoids, a class a natural products having immunosuppressive activity. Synthetic analogs of phainanoids, e.g., compounds that mimic the structure of the “western” part of the structure of the phainanoids and that contain the benzofuranone-4,5-spirocycle are described, as well as their synthetic intermediates, and their methods of synthesis.

This disclosure features chemical entities (e.g., a compound or a pharmaceutically acceptable salt, and/or hydrate, and/or cocrystal, and/or drug combination of the compound) that inhibit (e.g., antagonize) Stimulator of Interferon Genes (STING). Said chemical entities are useful, e.g., for treating a condition, disease or disorder in which increased (e.g., excessive) STING activation (e.g., STING signaling) contributes to the pathology and/or symptoms and/or progression of the condition, disease or disorder (e.g., (cancer) in a subject (e.g., a human). This disclosure also features compositions containing the same as well as methods of using and making the same.
