  Chemoselective oxidative hydrolysis of EWG protected α-arylamino vinyl bromides to α-arylamino-α′-bromoacetones

  摘要：

  Vinyl bromides bearing an arylamino group in the vicinal position are chemoselectively transformed into interesting alpha-arylamino-alpha'-bromoacetones through a straightforward oxidative hydrolysis promoted by calcium hypobromite under mild acidic conditions. Significantly, this particular combination [vinyl bromides and Ca(BrO)(2)] avoids bromination at both the aromatic ring and activated positions in groups substituting the amine nitrogen. The usefulness of this class of brominated ketones has been shown in a Wittig homologation. (c) 2013 Elsevier Ltd. All rights reserved.
