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
A short, efficient and general methodology for benzo[b]carbazolenaphthoquinones was developed via Pd‐catalyzed C‐H arylation process. This methodology was successfully applied to the synthesis of highly biologically active compound 5H–benzo[b]carbazole‐6,11‐diones. Additionally, one‐pot synthesis of benzo[b]phenazine‐6,11(5H,12H)‐dione derivatives was also explored in aqueous medium.
