A Gold‐ and Brønsted Acid Catalytic Interplay Towards the Synthesis of Highly Substituted Tetrahydrocarbazoles |
|
| Abstract: | The reaction of indoles and stabilized cyclopropyl alkynes under gold‐ and/or gold & Brønsted acid‐catalysis provided access to highly substituted tetrahydrocarbazoles. A mechanistic study revealed the complex mechanism underlying these processes and the opportunistic cooperation of Lewis and Brønsted acid‐catalysts towards the formation of complex molecular scaffolds. |
