Photo-Friesrearrangement using benzoheterocyclic compounds, which are widely used in pharmaceuticals, was studied. Under ultraviolet (UV) light, benzoheterocyclic compounds containing an N-acetyl group underwent rearrangement of the acyl group directly to the α-position past the adjacent bridgehead carbon. This environmentally friendly method could be useful in organic synthesis, the pharmaceutical
