In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Nickel-Catalyzed Decarboxylative Arylation of Heteroarenes through sp2 C-H Functionalization, published in 2014, which mentions a compound: 118994-89-1, Name is Ethyl oxazole-5-carboxylate, Molecular C6H7NO3, Computed Properties of C6H7NO3.
The direct decarboxylative arylation of hetereoarenes with benzoic acids through a nickel-catalyzed sp2 C-H functionalization process was developed. This process provides the first examples of decarboxylative cross-coupling reactions with aromatic acids through nickel catalysis and tolerates a variety of functional groups. Moreover, this method provides efficient access to 2-aryl-substituted azoles, an important structural unit in natural products, medicinal compounds, and functional materials.
