Thioether skeletons are widely present in drugs, natural products, functional materials, and life science. In the past decade, selective C–H functionalization of thioethers has been extensively studied to construct novel thioether derivatives. This mini-review systematically introduces recent advances field direct α-C(sp3)-H thioethers.

A hindered β-amino amide transient directing group effects di-trans-arylation of cyclohexanecarbaldehydes. The N-substituents are shown to affect yield and can enhance the rate arylation compared with α-amino acid. Addition a pyridone ligand further enhanced reactivity. reaction is successful for range aryl iodides, various substituted cyclohexane carboxaldehydes, providing functionalized products from simple feedstocks. mechanism proposed evoking enamine.
