  吡咯中的亲电取代。第5部分。二吡咯甲烷与芳二氮鎓离子的反应

  摘要：

  二吡咯甲烷在酸性溶液中与苯并重氮离子反应形成偶氮吡咯和甲醛。在低pH值下，亚甲基桥的裂解是由氢离子的侵蚀引起的，但在较高pH值下，ned重氮离子承担了这一作用。在苄基吡咯的反应中，检测到苯甲醇为产物，表明形成了苄基碳鎓离子。考虑这些研究与胆红素的范登伯格试验的相关性。

• Cu(I)/Bis(azaferrocene)-Catalyzed Enantioselective Synthesis of β-Lactams via Couplings of Alkynes with Nitrones

  As a consequence of the wide-ranging significance of beta-lactams (e.g., use as drugs and as chiral building blocks), a great deal of effort has been dedicated to the development of methods for their stereoselective synthesis. Although considerable progress has been achieved, nearly all of the approaches that have been described are based on the use of chiral precursors; direct catalytic enantioselective routes to beta-lactams are rare as well as limited in scope. In this communication, we establish that, using a new C2-symmetric planar-chiral bis(azaferrocene) ligand, we can generate beta-lactams with very good enantiomeric excess and cis diastereoselection via catalytic enantioselective Kinugasa reactions (couplings of alkynes with nitrones). Appealing attributes of this process include the ready availability of the starting materials, the functional-group tolerance of the reaction, and the convergency of the approach.
