  The effect of pre-existing stereocenters in the intramolecular asymmetric Stetter reaction

  摘要：

  A series of disubstituted cyclopentanones have been synthesized by the intramolecular Stetter reaction. Racemic substrates containing one chiral center were used, allowing us the opportunity to observe a parallel kinetic resolution in the synthesis of 2,3- and 2,4disubstituted cyclopentanones. The Stetter reaction of 2,5-disubstituted cyclopentanones proved to be substrate controlled, resulting in the selective formation of the cis-diasteroiners with low ee. (c) 2005 Elsevier Ltd.

• A Tandem Amino-Cope Rearrangement/Enamine Alkylation Reaction
  作者：Steven Allin、Martin Button、Stephen Shuttleworth

  DOI：10.1055/s-1997-3248

  日期：1997.6

  Thermally induced [3,3]-sigmatropic rearrangement of 3-amino-1,5-diene substrates occurs to give the corresponding enamine products in high yield and with excellent trans:cis enamine selectivity. The enamine produced during the amino-Cope rearrangement has been directly derivatized, representing the first report of a tandem amino-Cope rearrangement/enamine alkylation reaction. The potential of this novel synthetic strategy is outlined.

  热诱导的3-氨基-1,5-二烯底物的[3,3]-σ-转位重排反应生成相应的烯胺产物，产率高且具有优良的反式:顺式烯胺选择性。在氨基-科普重排反应中产生的烯胺已被直接衍生化，代表了串联氨基-科普重排/烯胺烷基化反应的首次报道。概述了这一新型合成策略的潜力。
