Pd-catalyzed annulation of aryne and aryl ketone O-acetyloxime via C-H bond activation was realized. Through the C-H bond activation/insertion/cyclization/elimination reaction sequence, phenanthridines are successfully constructed, providing an attractive strategy to approach substituted heterocycle without preactivation of starting materials.
