  Regioselective Trapping of Terminal Di-, Tri-, and Tetraynes with Benzyl Azide

  摘要：

  The reaction of benzyl azide with terminal di-, tri-, and tetraynes appended with a range of functional groups has been explored. Standard reaction conditions for BnN3 catalyzed by CuSO(4)(.)5H(2)O gave alkynyl, butadiynyl, and hexatriynyl triazoles in moderate to good yields. The reaction proceeds regioselectively as determined by the X-ray crystallographic analysis of three derivatives (1c, 1d, and 3c), and no evidence of multiple azide addition to the polyyne framework is observed.

  The synthesis and isolation is reported of five terminal aryl/biaryl-butadiynes, Ar–C≡C–C≡CH, (5a–c, 10a and 10b) from 2-methyl-6-aryl/biaryl-hexa-3,5-diyn-2-ol precursors [Ar–C≡C–C≡C–C(Me)2OH; Ar = 2-MeOC6H4, 3-MeOC6H4, 4-MeOC6H4, 2-phenylpyridin-5-yl, 3-phenylpyridin-2-yl, respectively]. The X-ray crystal structures have been obtained for compounds 5c and 10a. Surprisingly, no ≡C–H···X (X = N or

• An easy access to unsymmetrically substituted 4,4′-bi-1,2,3-triazoles
  作者：Vito Fiandanese、Daniela Bottalico、Giuseppe Marchese、Angela Punzi、Francesca Capuzzolo

  A convenient synthesis of 4-alkynyl-1,2,3-triazoles and novel unsymmetrically substituted 4,4'-bi-1,2,3-triazole derivatives has been devised starting from easily available 1-trimethylsilyi-1,3-butadiyne. The starting compound was reacted with several azides, leading to 4-(silylalkynyl)-1,2,3-triazoles, which were easily transformed into 4-arylalkynyl-1,2,3-triazoles by a Pd catalyzed coupling reaction with aryl halides, or into novel 4,4'-bi-1,2,3-triazole derivatives by a subsequent cyclization reaction with azides.

• Reactions of Terminal Polyynes with Benzyl Azide

  Terminal di-, tri-, tetra-, and pentaynes substituted with a variety of functional groups react with benzyl azide in the presence of CuSO4 center dot 5H(2)O and ascorbic acid to give derivatives of 4-ethynyl-, 4-butadiynyl-, 4-hexatriynyl-, and 4-octatetraynyl-,2,3-triazoles in moderate to good yields. These reactions appear to proceed regioselectively, and functionalization occurs exclusively at the terminal alkyne moiety. As well, no evidence of multiple azide additions to the polyyne framework is observed. X-ray crystallographic analysis of nine derivatives is used to document the regioselectivity of the reaction as well as outline structural characteristics of the 1,2,3-triazole products.
