Lewis Acid-Promoted Synthesis of Unsymmetrical and Highly Functionalized Carbazoles and Dibenzofurans from Biaryl Triazenes: Application for the Total Synthesis of Clausine C, Clausine R, and Clauraila A
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 cla...

Zusammenfassung: | 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). |
