  Intermolecular and Intramolecular α-Amidoalkylation Reactions Using Bismuth Triflate as the Catalyst

  摘要：

  Bismuth(III) triflate was found to promote the formation of stable cyclic N-acyliminium species in remarkable catalytic amounts (1 mol %). The alpha-amidoalkylation process seems to be effective in intermolecular and intramolecular manners leading to alpha-substituted lactams and heterocyclic systems containing azacycles, respectively. By comparing our results with those obtained with the classical Lewis acids as catalysts, it was evidenced clearly that the use of bismuth(III) triflate had been efficient for nearly all alpha-acetoxy lactams we used, except for N-acyliminium precursors bearing a sulfur atom. Also, the process seems to be easy, general, and clean, having diastereoselectivity comparable to protocols using classical Lewis acids and resulting in the formation of polyheterocyclic systems in good to excellent yields (64-99% in acetonitrile as solvent).

  A new approach for the synthesis of isoindoloquinoline and aromathecin templates is presented. These were obtained in a few steps starting from inexpensive reagents by two different strategies. The key step for both sequences was the IMFDA reaction, leading diastereoselectively to the formation of the unsaturated DE ring system of the expected alkaloid skeletons.

  本文介绍了一种合成异吲哚喹啉和芳香霉素模板的新方法。从廉价的试剂开始，通过两种不同的策略，只需几步就能获得这些试剂。两个序列的关键步骤都是 IMFDA 反应，该反应导致非对映选择性地形成预期生物碱骨架的不饱和 DE 环系统。
