“…While traditional cross‐coupling reactions of halogenated 2‐pyridones are still widely employed to access functionalized 2‐pyridone derivatives, [10] direct functionalization of 2‐pyridone C−H bonds using transition‐metal catalysts has recently evolved as an efficient and versatile synthetic tool for producing such products in a highly step‐ and atom‐economical manner with promising results being achieved in regioselective functionalization of 2‐pyridones at the positions of C3, C4, C5 and C6 [11] . In particular, since the seminal work by Hirano and Miura on the introduction of a pyridine group on the nitrogen atom of the 2‐pyridone skeleton to promote C6‐selective heteroarylation of 2‐pyridones, [12a] chelation‐assisted direct alkylation, [12b,i,j,m,o,s,t] arylation, [12f,h,k] borylation, [12e] thiolation, [12g] annulation, [12c,d,l,n] and amidation [12p–r] of 2‐pyridones at the C6 positions using transition‐metal catalysts have been successfully realized, mainly involving rhodium and ruthenium complexes. Nevertheless, there are surprisingly few examples of direct C−H alkenylation of 2‐pyridones at the C6 position despite the potential utility of such products [5d,13] .…”
