  New Insights into NIS-Promoted Aminocyclization. Synthesis of Decahydroquinolines from 2-Allylcyclohexylamines

  摘要：

  Bishomoallylic secondary amines embodying the 2-allyl-N-benzylcyclohexylamine unit react with NIS to undergo cyclization through 6-endo processes in either the cis or trans series. Nevertheless, when the resulting cis-3-iododecahydroquinolines are treated with Al2O3, the exo derivatives evolve into octahydroindoles and the endo derivatives keep the same backbone, the configuration being retained in the generated alcohols.

• Palladium-Catalyzed Aerobic Oxidative Cyclization of Aliphatic Alkenyl Amides for the Construction of Pyrrolizidine and Indolizidine Derivatives
  作者：Dan Yang、Kai-Yip Lo、Liu Ye

  DOI：10.1055/s-0036-1588502

  日期：2017.8

  An efficient palladium-catalyzed aerobic oxidative cyclization has been developed to synthesize a variety of pyrrolizidine and indolizidine derivatives from simple aliphatic alkenyl amides in moderate to good yields. The reaction features the capability of accessing various N-heterocycles and the use of molecular oxygen (1 atm) as the green oxidant.

  The first examples of 1,3,2-diazaphospholene-catalyzed imine reduction and conjugate reduction reactions are reported. This approach employs readily synthesized alkoxydiazaphospholene precatalysts that can be handled in open air. Reduction of substrates containing Lewis basic functionality, isolated unsaturation, and protic functional groups was accomplished. The synthetic utility of this approach

  The transfer hydrogenation of 2-substituted bicyclic and monocyclic ketimines using HCO2H/ Et3N as the hydrogen source and TsDPEN-based Ru(II) and Ir(III) catalysts proceeds with dynamic kinetic resolution to afford the corresponding cis-cycloalkylamines with moderate to excellent levels of diastero- and enantioselectivity.
