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.
Heterocyclic pentafluorophenyl sulfonate esters as shelf stable alternatives to sulfonyl chlorides
Bornholdt, Jan,Fj?re, Karianne Wilhemsen,Felding, Jakob,Kristensen, Jesper Langgaard
experimental part, p. 9280 - 9284 (2010/01/16)
Heterocyclic pentafluorophenyl sulfonate esters are shelf stable alternatives to the often less stable sulfonyl chlorides. They are easily prepared from thiols and react readily with primary and secondary amines to produce sulfonamides in high yields.
