title: Synthesis of Carbazolequinones by Formal [3 + 2] Cycloaddition of Arynes and 2-Aminoquinones.
abstract: A formal cycloaddition reaction for the synthesis of biologically and pharmaceutically important carbazolequinones via the annulation of aminoquinones with arynes has been developed. This practical and metal-free cascade reaction proceeds through successive C-C/C-N bond formations. Moreover, this novel method has been utilized for the concise synthesis of bioactive murrayaquinone A and koeniginequinone B and their analogues.
