Photoredox　catalysis　has　become　a　mainstay　in　synthetic　methodology　over　the　past　decade.　However,　its　application　in　the　functionalization　of　natural　products　remains　to　be　further　explored.　Herein,　we　report　an　efficient　approach　to　synthesize　artemisinin　G　from　artemisinin　via　photocatalysis　in　high　yield.　Photoredox　catalysis　has　become　a　mainstay　in　synthetic　methodology　over　the　past　decade.　Herein,　an　efficient　method　for　the　synthesis　of　artemisinin　G　from　artemisinin　by　using　0.5　mol　%　of　TBADT　as　the　catalyst　was　reported.　The　reaction　proceeds　smoothly　and　rapidly　(complete　within　30　min)　at　room　temperature　in　high　yield.　image
