Transition-metal-free radical difluorobenzylation/cyclization of unactivated alkenes: access to ArCF ₂ -substituted ring-fused quinazolinones

A mild and efficient transition metal-free radical difluoroarylmethylation/cyclization of unactivated alkenes toward the synthesis of quinazolinone derivatives with easily accessible α,α-difluoroarylacetic acids has been developed.
