Medium-sized rings show great potential in medicinal chemistry but are difficult to achieve via direct cyclization reaction. We herein report a versatile and mild photocatalytic approach for synthesis of medium- large-sized vinyl N-heterocycles by radical-mediated sulfonamides with pendant 1,3-dienes. The reaction involves the generation radicals from alkyl halides π-allylpalladium species. This method could serve as platform construction Pd catalysis.
