A novel gold-catalyzedintermolecular oxidation of o-ethynylanilines has been developed. A range of functionalized 3-oxyindoles are readily accessed by utilizing this strategy. Importantly, this gold-catalyzed oxidative process outcompetes the typical indole formation.

4-Amino-6-(heterocyclic )picolinic acids, 6-amino-2-(heterocyclic )pyrimidine-4-carboxylates, and derivatives thereof are provided. Also provided are herbicidal compositions including these compounds, as well as methods of using thereof as herbicides. The occurrence of undesirable vegetation, e.g., weeds, is a constant problem facing famers in crops, pasture, and other settings. Weeds compete with crops and negatively impact crop yield. The use of chemical herbicides is an important tool in controlling undesirable vegetation.
