  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.

  A diastereoselective protocol has been established for the synthesis of 4-O-tosyl piperidine containing hexahydroindolizin-3(2H)-one, hexahydro-1H-quinolizin-4(6H)-one and 1,3,4,10b-tetrahydropyrido[2,1-a]isoindol-6(2H)-one derivatives via the aza-Prins cyclization reaction of cyclic N-acyliminium ions mediated by p-toluene sulphonic acid (p-TSA) under mild conditions. The reaction is highly diastereoselective

  The preparation of 2,6-substituted piperidine derivatives through diastereoselective C–H functionalization of corresponding nitrogen heterocycles represents an appealing protocol and yet remains a formidable challenge. Here, we describe a stereochemically complementary oxidative C–H functionalization of N-carbamoyl tetrahydropyridines with a wide variety of building blocks, providing either the cis-

  (±)-Indolizidines 167B and 209D, their epimers and (±)-tashiromine have been successfully synthesized, starting from simple γ- or α-lactams. The strategy involves the cyclization of α-sulfinyl carbanion onto the carbonyl group of the lactam ring as the key step, leading to the indolizidines containing the phenylsulfinyl group, which are used as precursors for the preparation of the title compounds

  intramolecular cyclization oftrans- andcis-2-allyl-6-R-1,2,3,6-tetrahydropyridines, obtained from pyridine and triallylborane, has been elaborated. The closure of the five-membered ring is carried out by hydroboration-oxidation followed by cyclization of the resulting δ-amino alcohols in the presence of the Ph3P−CBr4−Et3N system. (Pr2BH)2 and Pr3B are used as the hydroborating reagents, and H2O2 in an acid medium
