  A Kulinkovich Entry into Tertiary N-Acyliminium Ion Chemistry

  摘要：

  [GRAPHICS]Subjection of N-alkenylimides to Kulinkovich cyclopropanation conditions led to different types of N,O-acetals, which were used as precursors for tertiary N-acyliminium ion chemistry. In this way, a variety of bi- and tricyclic lactams were efficiently synthesized.

• Synthetic Studies Toward caphalotaxine: Functionalization of Tertiary N-Acylhemiaminals by Nazarov Cyclization
  作者：Se-Ho Kim、Jin Kun Cha

  DOI：10.1055/s-2000-8711

  日期：——

  Functionalization of bicyclic N-acylhemiaminals, which are readily available by titanium-mediated intramolecular coupling of vinyl-tethered imides, has been achieved by use of the Nazarov cyclization to construct the carbon-carbon bond at the quaternary center. This synthetic strategy allows rapid entry to the key structural elements of cephalotaxine.

  已实现对双环N-酰基半胺的功能化，这些化合物可以通过钛介导的乙烯连接的酰胺的分子内偶联容易获得，使用Nazarov环化反应在四级中心构建碳-碳键。这一合成策略使我们能够快速进入颅税素的关键结构元素。
