Photocatalytic radical sulfonamidation/cyclization cascade towards sulfonaminated dihydrofurans and dihydroisoxazoles

A general visible light induced photoredox‐catalyzed radical sulfonamidation/cyclization cascade of olefinic carbonyls and β,γ‐unsaturated oximes is described under mild and metal‐free conditions. The protocol enables an efficient access to various sulfonaminated dihydrofurans and dihydroisoxazoles with moderate to good yields.
