  Acetyltrimethylsilane mediated synthesis of dihydrophenanthrenes

  摘要：

  An easy and efficient synthesis of phenanthrene derivatives through base catalyzed ring transformation of 4-sec-amino-2oxo-5,6-dihydro-2H-benzo[h]chromene-3-carbonitrites with acetyltrimethylsilane is described in good yields. The advantage of this reaction is the direct transformation of 2-oxobenzo[h]chromene into phenanthrene via C-C insertion from acetyltrimethylsilane. (c) 2007 Elsevier Ltd. All rights reserved.

  functionalized 2H-pyran-2-ones has been demonstrated for the synthesis of various multi-substituted benzenes through a tandem process. We observed that lithium hydroxide provides a major product from α-attack and a minor product from γ-attack of allyl cyanide, while the use of sodium hydride as a base exclusively provides the product by γ-attack of allyl cyanide. We have also performed NMR experiments to understand
