of R chains of amides R1C(O)NHR, a fundamental class of synthetic substrates, has not been accomplished to date. Here, the first example of palladium(II)-catalyzed alkynylation of an unactivated gamma C(sp3)–H bond of alkyl amides (cyclic, linear, and amino acids) is reported. The kinetic experiment shows that the rate of the reaction depends on the coupling partners and the amides. Late-stage diversification

)—H alkynylation of amines using picolinamide as directing group. The developed alkynylation strategy is simple, efficient, and tolerant of various ring size including five to eight member cyclic, quaternary amines, and N-heterocyclic motifs.
In the presence of a supported gold–palladium alloy nanoparticle catalyst (Au–Pd/Al2O3), various kinds of N-substituted anilines can be synthesized from non-aromatic compounds.

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.
