  DOI：10.1002/chem.201102802

  日期：2011.12.2

  A natural approach: A Lewis acid‐promoted nucleophilic aromatic substitution approach to the regioselective synthesis of highly substituted carbazoles and dibenzofurans has been developed. The annulation process is applied to the total synthesis of carbazole alkaloids clausine C, clausine R, and clauraila A (see scheme).
