  One pot conversion of azido arenes to N-arylacetamides and N-arylformamides: synthesis of 1,4-benzodiazepine-2,5-diones and fused [2,1-b]quinazolinones

  摘要：

  Sodium iodide in acidic media has been employed for the synthesis of N-arylformamides and N-arylacetamides. The NaI/acetic acid reagent system has also been extended for the synthesis of 1,4-benzodiazepine-2,5-diones, pyrrolo[2,1-c][1,4]benzodiazepine-5,11-diones, and fused [2,1-b]quinazolinones.

  triflates catalyze the chemoselective reduction of aromatic azides to the corresponding amines in combination with sodium iodide. This mild chemoselective method has been applied to the synthesis of various aryl amines, C2‐azido‐substituted pyrrolo[2,1‐c][1,4]benzodiazepines, and fused[2,1‐b]quinazolinones by an intramolecular azido reduction tandem cyclization reaction. Interestingly, this methodology

  铝和ado三氟甲磺酸盐与碘化钠一起催化将芳族叠氮化物化学选择性还原为相应的胺。这种温和的化学选择性方法已应用于各种芳基胺的合成，C2叠氮基取代的吡咯并[2,1- c ^ ] [1,4]苯二氮，和稠合[2,1- b通过分子内还原叠氮]喹唑啉酮串联环化反应。有趣的是，这种方法选择性地还原了芳基叠氮化物，提高了产率，并且比以前的策略在较短的反应时间内进行。已对机理进行了研究，并通过ESI-MS在线监测反应来拦截和表征与这种选择性转化有关的中间体。

  An efficient preparation of fused [2,1-b]quinazolinones has been developed utilizing polymer-supported reagents. (±)-Vasicinone was converted into its dione by oxidation with poly (4-vinylpyridiniumdichromate). An efficient method has been developed for the synthesis of (d)- and (l)-vasicinone via asymmetric reduction of pyrrolo[2,l-b]quinazoline-3,9-dione by employing NaBH 4 /Me 3 SiCl as the reducing

  skeletons occupy a prominent position in drug discovery. Even with currently available methods there still remain unmet needs for flexible access to such structures. Herein, we have explored a mild “one pot” procedure for the construction of various quinazolinone-[2,3]-fused polycycles. The procedure involves Pd-catalyzed carbonylation of N-(2-iodophenyl)acetamides, release of the masked terminal amine

  多种喹唑啉酮-[2,3]-稠合多环骨架在药物发现中占据着重要地位。即使采用当前可用的方法，对于灵活访问此类结构的需求仍然未得到满足。在此，我们探索了一种温和的“一锅法”程序来构建各种喹唑啉酮-[2,3]-稠合多环。该过程包括 Pd 催化的N- (2-碘苯基)乙酰胺的羰基化、掩蔽末端胺的释放以及两个连续的自发环化。这种普遍适用的方法具有从容易获得的起始材料中轻松组装前体、反应条件温和、操作不繁琐和多环多样性的特点。
