  Modular Synthesis of N-Vinyl Benzotriazoles

  摘要：

  A modular approach to N1-vinyl benzotriazoles by azide-aryne cycloadditions and Julia-Kocienski reactions is described. Reactions of azidomethyl phenyl-1H-tetrazol-5-yl (PT) sulfide with arynes gave methyl(PT-sulfanyl)-substituted benzotriazoles in 68-89% yields. Oxidation of the sulfides to the sulfones gave the benzotriazole-substituted Julia-Kocienski reagents. Olefination reactions of aldehydes and a ketone with reagents derived from benzyne, 2,3-naphthyne, and 4,5-dimethoxybenzyne precursors proceeded to give various NI-vinyl benzotriazole derivatives. Olefination stereoselectivities are tunable for electron-rich aldehydes, but not for electron-deficient aldehydes and alkanals, where they proceed with good to excellent Z-stereoselectivity.

• Stereoselective Synthesis of <i>Z</i> Alkenyl Halides via Julia Olefination
  作者：Marie-Eve Lebrun、Paul Le Marquand、Carl Berthelette

  DOI：10.1021/jo052370h

  日期：2006.3.1

  Julia olefination between alpha-halomethyl sulfones and a variety of aldehydes afforded alkenyl halides in good to excellent yields with high E/Z stereo selectivities. Sulfones were readily prepared in two or three steps from commercially available reagents in good yields. Optimization revealed that the nature of the Z solvent, the base, and the additive were crucial to obtain the desired alkenyl halides.
