  SmI2-mediated hetero-coupling reaction of lactams with aldehydes; synthesis of indolizidine alkaloids, (−)-δ-coniceine, (+)-5-epiindolizidine 167B and (+)-lentiginosine

  摘要：

  Treatment of alicyclic and aromatic lactams with several aldehydes in the presence of samarium(II) diiodide was found to undergo a novel nitrogen-carbon (hetero) coupling reaction to generate N-alpha -hydroxyalkylated lactams in high yield. The chiral lactams with an aldehyde-side chain incorporating the L-pyroglutamic acid- or L-tartaric acid-derived skeleton also reacted intramolecularly under the same conditions to afford the corresponding bicyclic coupling products, which were further applied to the convenient syntheses of (-)-delta -coniceine, (+)-5-epiindolizidine 167B and (+)-lentiginosine, respectively.
