irinotecan and SN‐38 were successfully synthesized by a photocatalyzed radical cascade cyclization from an N‐propargyl iodopyridinone and an arylisonitrile undervisiblelight with a ruthenium catalyst. This synthetic method provided a useful entry into composing camptothecin family of antitumor agents in good yields undermild reaction conditions without the use of heavy metal reagents.
