  Facile synthesis of 1,4-diketones via palladium complex catalyzed isomerization of alkynediols

  摘要：

  Alkynediols isomerized under the catalysis of Pd2(dba)3.CHCl3 + 2n-Bu3P in acetonitrile at 80-degrees-C to give 1,4-diketones in high yields. This experimentally simple and economically synthetic method is illustrated with examples including substituents such as alkyl, alkenyl, and aryl groups. The order of reactivity of the substituents in this reaction is aryl greater-than-or-equal-to alkenyl > alkyl. Alkenyl-substituted alkynediols chemoselectively isomerized to the corresponding alpha,beta-unsaturated 1,4-diketones. The usefulness of this novel method is exemplified by the synthesis of dihydrojasmone.

  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

  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.
