• General Strategy for the Synthesis of Natural and Unnatural Dialkylmaleic Anhydrides
  作者：Kishan P. Haval、Narshinha P. Argade

  DOI：10.1021/jo801284r

  日期：2008.9.1

  Starting from alkylidenesuccinimides, a wide range of dialkylmaleic anhydrides have been synthesized via the generation of a carbanion on a succinimide unit and its condensation with various alkyl halides as the key reaction.

  从亚烷基琥珀酰亚胺开始，已经通过在琥珀酰亚胺单元上产生碳负离子并与各种烷基卤化物缩合为关键反应，合成了多种二烷基马来酸酐。
• Haval–Argade contrathermodynamic rearrangement of alkylidenesuccinimides to alkylmaleimides via the corresponding isoimides: a general approach to alkyl and dialkyl substituted maleimides

  A simple and efficient access to alkyl and dialkyl substituted maleimides has been demonstrated via the new contrathermodynamic rearrangement of (E)-alkylidenesuccinimides to alkylinaleimides. The (E)-alkylidenesuccinimides obtained from the Wittig-condensation of N-arylmaleimide with aliphatic aldehydes oil regioselective hydrolysis furnished the corresponding (E)-alkylidenesuccinanilic acids in 95-98% yields. The beta-alkylidenesuccinanilic acids oil treatment with cyanuric chloride in the presence of triethylamine gave the corresponding beta-alkylisomaleimides in 78-80% yields via the beta-alkylideneisosuccinimides with the exocyclic to endocyclic carbon-carbon double bond migration. The kinetically controlled products alkylisomaleimides in refluxing acetic acid furnished the thermodynamically controlled alkylinaleimides in 98% yield. The Wittig condensation of alkyl substituted isomaleimides/maleimides with aliphatic aldehydes gave the desired dialkyl substituted maleimides in high yields. A conversion of alpha-methylenesuccinanilic acids to alpha-methylisomaleimides has also been described, with 90% yield. (c) 2006 Elsevier Ltd. All rights reserved.
