  Development of Methods for the Synthesis of Libraries of Substituted Maleimides and α,β-Unsaturated-γ-butyrolactams

  摘要：

  Synthetic methods for the preparation of maleimide and alpha,beta-unsaturated-gamma-butyrolactam compound collections are described. These routes take advantage of Pd cross-coupling and conjugate addition/elimination reactions to permit the facile production of bisaryl-maleimides, anilinoaryl-maleimides, and bisanilino-maleimides while allowing control over the synthesis of symmetrical or nonsymmetrical derivatives. Similarly, the chemistry developed allows for the generation of bisaryl substituted alpha,beta-unsaturated-gamma-butyrolactams. The scope and limitations of the approaches are presented.

  New routes toward selective synthesis of both mono- and diaryl maleimides have been innovated. The mere requirement to this end is through the increase of temperature. The method works effectively for maleic anhydride and maleic acid as well. Also, the first expedient synthesis of 2-arylnaphthoquinones via the reaction of naphthoquinone with arenesulfonyl chlorides is revealed.

  创新了单和二芳基马来酰亚胺选择性合成的新途径。为此目的的唯一要求是通过升高温度。该方法对马来酸酐和马来酸也有效。另外，揭示了通过萘醌与芳烃磺酰氯的反应的2-芳基萘醌的第一种方便的合成方法。
