achieved on the basis of base-mediated intramolecular C−C bond formation. Reactions of N-substituted o-halodiarylamines with potassium tert-butoxide in the presence of ethylene glycol or 1,10-phenanthroline provided carbazoles in moderate to excellent yields. This transformation may proceed via the radicalpathway according to the control experiment with a radical scavenger.

Affinity reagents are often used to address the target identification problem in chemical genetics. The design of such reagents so that the linker does not occlude interactions with protein targets is an ongoing challenge. This work describes a systematic approach to synthesize derivatives of a bioactive that should avoid interference with binding to targets and be readily converted to affinity reagents.
