Because benzannulated and indole-fused medium-sizedrings are found in many bioactive compounds, combining these fragments might lead to unexplored areas of biologically relevant and uncovered chemical space. Herein is shown that α-imino gold carbene chemistry can play an important role in solving the difficulty in the formation of medium-sizedrings. Namely, phenylene-tethered azido-alkynes undergo
