  Double Reduction of Cyclic Aromatic Sulfonamides:  A Novel Method for the Synthesis of 2- and 3-Aryl-Substituted Cyclic Amines

  摘要：

  The facile double reduction of bicyclic aromatic sulfonamides was used to synthesize a variety of 2- and 3-aryl-substituted pyrrolidines and 2-phenylpiperidine. The method features a combined nitrogen protection and a traceless tether for the transposition of the aromatic moiety from nitrogen to carbon.

• Synthesis of Polycyclic Lactams and Sultams by a Cascade Ring-Closure Metathesis/Isomerization and Subsequent Radical Cyclization
  作者：Olivier Piva、Cyril Bressy、Christine Menant

  DOI：10.1055/s-2005-862386

  日期：——

  Starting from readily available substrates, a new one-pot procedure has been devised to prepare polycyclic lactams and sultams. 2-Pyrrolines obtained from N,N-bisallylamides by ring-closure metathesis and subsequent isomerization promoted by ruthenium hydride complexes can undergo radical cyclization to furnish polycyclic lactams in good yields. The process was successfully conducted on bisallylsulfonamides to give the corresponding sultams.

  从易得的底物出发，设计了一种新的一步法程序来制备多环内酰胺和内磺酰胺。通过环闭重排和随后由钌氢复合物促进的异构化，获得的2-吡咯啉可以进行自由基环化，良好产率地生成多环内酰胺。该过程成功应用于双丙烯基磺酰胺，生成相应的内磺酰胺。
