Diastereoselective construction of complex spiroheterocycles via γ-C(sp 3 )–H functionalization of 1,1-disubstituted cyclohexanes with diverse bifunctional reagents

Visible-light-driven, metal- and additive-free radical cascade enables diastereoselective synthesis of spirocyclic-azaspiro[4.5]decanes from 1,1-disubstituted cyclohexanes using diverse sulfonyl bifunctional reagents.
