Synthesis of an N-protected 2-bromo- 1H-carbazole-1,4(9H)-dione is reported for the first time. We took full advantage of the high polarization and electrophilic properties of this new compound to engage it in a regioselective hetero-Diels-Alder reaction. The resultant cycloadduct was next transformed to an isomer of the naturally occurring calothrixin B displaying a new 7H-indolo[2,3-j]phenanthridine-7,13(8H)-dione structure.
