  Radical cation salt induced Povarov reaction between iminoethyl glyoxylate and N-vinylamides: synthesis of quinoline-2-carboxylate derivatives

  摘要：

  A domino process between iminoethyl glyoxylate and N-vinylamides was achieved under the catalytic radical cation salt induced conditions, producing a series of quinoline-2-carboxylates. N-Vinylamides were involved as an acetylene equivalent. A possible mechanism was proposed to rationalize the formation of the products. (C) 2012 Elsevier Ltd. All rights reserved.

  摘要：

  已经证明，通过反电子需求的氮杂Diels-Alder环加成反应和N-芳基化反应，可以实现芳烃，苯胺和乙醛酸乙酯的无过渡金属多组分偶联。该方案允许在室温下从容易获得的起始原料以中等至高产率快速获得N-芳基二氢菲啶衍生物。此外，前所未有的氟化物诱导的（芳基）乙酸乙酯的环化反应在温和条件下以高收率导致形成高度官能化的氧代咪唑烷衍生物。

  Diels−Alder (Povarov) reactions leading diastereoselectively to hexahydrobenzo[h][1,6]-naphthyridine derivatives containing three adjacent stereocenters. The synthesis of fused dihydropyridines derived from the pyrido[2,1-a]azepine (homoquinolizine) frameworks was also achieved using a four-component tetrahydropyridine synthesis/ring-closing metathesis/elimination strategy.
