Previous approaches to 4-azafluorenone alkaloid syntheses featuring 2-arylnicotinates are supplemented with tert-butyl hydroperoxide-mediated radical cyclization and/or bromine substituents as latent hydroxy groups which allows for flexible synthesis of highly oxygenated 4-azafluorenone alkaloids, including 5-oxygenated derivatives inaccessible via conventional Friedel-Crafts-type cyclization of 2-arylnicotinates
