  A cobalt‐catalyzed 1,4‐aryl migration/disulfonylation cascade applied to α‐bromo N‐sulfonyl amides was developed. The reaction was highly chemoselective, allowing the preparation of α‐aryl amides possessing a variety of functional groups. The method was used as the key step to synthesize an alkaloid, (±)‐deoxyeseroline. Mechanistic investigations suggest a radical process.
