  Application of a Sequential Multicomponent Assembly Process/Huisgen Cycloaddition Strategy to the Preparation of Libraries of 1,2,3-Triazole-Fused 1,4-Benzodiazepines

  摘要：

  A strategy featuring a multicomponent assembly process followed by an intramolecular azide-alkyne dipolar (Huisgen) cycloaddition was implemented for the facile synthesis of three different 1,2,3-triazolo-1,4-benzodiazepine scaffolds. A diverse library of 170 compounds derived from these scaffolds was then created through N-functionalizations, palladium catalyzed cross coupling reactions, and several applications of alpha-aminonitrile chemistry.

  process to give an intermediate azido alkyne that undergoes a facile Huisgen dipolar cycloaddition. The triazolo-1,4-benzodiazepines thus produced may be endowed with aryl halide, secondary amino, alcohol, aldehyde or carboxylic acid groups as functional handles for orthogonal derivatization reactions. Modification of this approach enabled the facile synthesis of the related triazolo-1,4-benzodiazepin-6-ones

  描述了高效，简明的路线，获取了新颖的三唑并-1,4-苯并二氮杂sc骨架，这些骨架经过适当的官能化处理，可以在三个位置进行多样化，以探索具有不同取代基的三维空间。这些支架的一种方法具有简化的多组分组装过程，可得到中间体叠氮基炔烃，该中间体可进行简单的惠斯根偶极环加成反应。如此产生的三唑并1,4-苯并二氮杂may可被赋予芳基卤，仲氨基，醇，醛或羧酸基团作为正交衍生化反应的功能性处理。对该方法的改进使得可以容易地合成相关的三唑-1,4-苯并二氮杂-6-酮，也带有三个功能性手柄。

  A substituted heterocyclic scaffold comprising a 1,4-benzodiazepine fused with a 1,2,3-triazole ring has been synthesized and diversified via a variety of refunctionalizations. The strategy features the rapid assembly of the scaffold by combining 3−4 reactants in an efficient multicomponent assembly process, followed by an intramolecular Huisgen cycloaddition.
