Meta-selective C–H functionalization copper catalyzed C–H arylation. "Meta"-olefinated biologically important biphenyl, amino acid and Baclofen derivatives have been accessed by remote C–H activation assisted by the "end-on" template. These demonstrate the potential applications of meta-selective C–H functionalization in medicinal chemistry. Meta-selective C–H functionalization "Meta"-selective C–H functionalization refers to the regioselective reaction of a substituted aromatic ring on the C–H bond "meta" to the substituent. Substituted aromatic ring is an important type of substructure in pharmaceuticals and industrial compounds. Thus, synthetic methods towards substituted aromatic rings are always of great interest to chemists. Traditionally, regioselectivity on the aromatic ring is achieved by the electronic
