  Rhodium(I)-Catalyzed [2 + 2 + 2] Cycloaddition Reactions of Triacetylenic 15-Membered Aza Macrocycles: A Comparative Structural Study

  摘要：

  A variety of new nitrogen-containing 15-membered triacetylenic macrocycles with one or two alkyl substituents in a propargylic position have been efficiently synthesized and completely characterized. These macrocyclic systems undergo [2 + 2 + 2] cycloaddition reactions, leading to the corresponding fused tetracycles with a benzene core on treatment with Wilkinson's catalyst, [RhCl(PPh3)(3)]. The effects of alkyl chains have been evaluated on both the efficiency of the reaction and the conformational and structural analysis of the reactants.

  Various 1,2,5-substituted pyrroles have been synthesised from 1,4-alkynediols using a ruthenium catalysed isomerisation to give the corresponding 1,4-dicarbonyl compounds, which undergo in situ cyclisation to pyrroles in the presence of amine. (C) 2007 Published by Elsevier Ltd.

  Alkyne-1,4-diols are readily available substrates which are isomerised to 1,4-diketones using Ru(PPh3)(3)(CO)H-2/xantphos as a catalyst. In situ cyclisation into furans, pyrroles and pyridazines has been achieved under suitable conditions. (C) 2009 Elsevier Ltd. All rights reserved.
• 2,5-Disubstituted furans from 1,4-alkynediols
  作者：Simon J. Pridmore、Paul A. Slatford、Jonathan M.J. Williams

  DOI：10.1016/j.tetlet.2007.05.069

  日期：2007.7

  1-4-Alkynediols serve as readily available starting materials for isomerisation to 1,4-diketones, which can be converted in situ into the corresponding furans by acid-catalysed dehydration. A range of 2,5-disubstituted furans was prepared using the ruthenium-based catalyst Ru(PPh3)(3)(CO)H-2 with Xantphos at 1 mol % loading. (C) 2007 Published by Elsevier Ltd.
