1,3,7,9,11,12,14‐Heptazapentacene‐2,4,8,10(14 H ,3 H ,9 H ,12 H )‐tetraones (mixed flavins) were synthesized by the cyclization of 1,5‐dihydro‐8‐[ N ‐alkyl‐ N ‐(5‐nitrouracil‐6‐yl)]‐amino‐5‐ deazaflavins with the Vilsmeier reagent. The mixed flavins oxidized alcohol under neutral conditions in sunlight.
