A Novel C–N Migration Rearrangement Based on N–F Compounds for the Synthesis of N-Alkyl Diaryl Ureas

A novel rearrangement reaction based on the structure of N-fluoro-N-(phenylsulfonyl) benzamides (FPSBA) was developed. In the presence of base, unsymmetrical N-alkyl diaryl ureas were obtained in good yields which were accomplished through secondary alkyl phenylamines initiated 1,2-phenyl-shift migration rearrangement of N-fluoro-N-(phenylsulfonyl) benzamides. The reaction was carried out without using traditional, highly toxic reagents and noble metals. Whereas without rearrangement occurrence for primary phenylamines and aliphatic amines, normal amides and N-(phenylsulfonyl) benzamides were afforded respectively. Nitrene and phenyl isocyanate included process were prevented and a secondary alkyl phenylamine initiated vicinal SN2' reaction occurred. This rearrangement reaction features an interesting reaction mechanism, mild reaction conditions, simple operation, and useful products.

A fast and convenient method using the Mukaiyama reagent was developed to prepare acyl sulfonamides from carboxylic acids and sulfonamides. This methodology is effective for a range of acids and sulfonamides proceeding in moderate to good yields with the
