P <sub>4</sub> S <sub>10</sub> ‐Promoted [5+1] Spiroannulation of 2‐(2‐Nitrophenyl)‐indoles with Cyclic Ketones to Access Spirocyclic Tetrahydrocarbolines
A P 4 S 10 ‐promoted [5 + 1] spiroannulation of 2‐(2‐nitrophenyl)‐indoles with cyclic ketones for the preparation of spirocyclic tetrahydrocarbolines has been described. The present approach afforded a series of structurally valuable spirocyclic tetrahydrocarbolines in moderate to good yields under metal‐free conditions. In this work, nitro reduction, C–N condensation, and spiroannulation were realized in one pot.
