  • Synthesis of xylal‐ and arabinal‐based crown ethers and their application as asymmetric phase transfer catalysts

    from l‐ and d‐xylose, and l‐ and d‐arabinose, respectively. These monosaccharide‐based chiral macrocycles were tested as phase transfer catalysts in a few asymmetric reactions. The xylal‐based crown compounds proved to be efficient catalysts in a few liquid‐liquid phase reactions. The epoxidation of trans‐chalcone and the Darzens condensation of α‐chloroacetophenone with benzaldehyde took place with

  • Phase-transfer catalysed asymmetric epoxidation of enones using N-anthracenylmethyl-substituted Cinchona alkaloids
    作者:B. Lygo、P.G. Wainwright
    DOI:10.1016/s0040-4020(99)00205-7
    日期:1999.5
    A study into the enantioselective epoxidation of alpha, beta-unsaturated ketones utilising Cinchona alkaloid-derived quaternary ammonium phase-transfer catalysts bearing an N-anthracenylmethyl function is presented. It has been found that the O-benzyl derivatives of these catalysts in conjunction with sodium hypochlorite give high enantio and diastereoselectivities in the epoxidation of a range of substates (RCH)-C-1=CHCOR2, where R-1=alkyl or aryl and R-2=aryl. In the cases where R-2=alkyl high enantioselectivity has also been observed however the rate of reaction is substantially reduced. Application of this process to the enantioselective synthesis of a range of trans-alpha, beta-epoxy ketones (e.e. 90%) is presented. (C) 1999 Elsevier Science Ltd. All rights reserved.
