  Synthesis of aryl ring-fused benzimidazolequinones using 6-exo-trig radical cyclizations

  摘要：

  The preparation of alicyclic ring-fused tetracyclic and pentacyclic benzimidazoles containing one and two fused aryl rings, respectively, is achieved conveniently in three steps, including Bu3SnH-mediated 6-exo-trig cyclization of sigma-aryl radicals generated from 1-allyl-2-(omega-bromoaryl)benzimidazoles. Inclusion Of 4,7-dimethoxy substituents on the radical precursors allows access to aryl ring-fused benzimidazolequitiones, a Unique family of potential bioreductive anti-cancer agents.

• Construction of Binuclear Benzimidazole-Fused Quinazolinones and Pyrimidinones Using Aryl Isocyanates as Building Blocks by Transition-Metal-Free C(sp²)–N Coupling
  作者：Pham Duy Quang Dao、Chan Sik Cho

  of binuclear N-fused hybrid scaffolds was constructed by the reaction of 2-(2-bromoaryl)- and 2-(2-bromovinyl)benzimidazoles with aryl isocyanates as building blocks in the presence of a base under microwave irradiation. A nucleophilic addition followed by an unprecedented transition-metal-free C(sp2)–N coupling is proposed as a reaction pathway of this green process.

  通过使2-（2-溴芳基）-和2-（2-溴乙烯基）苯并咪唑与异氰酸芳基酯作为结构单元，在微波辐射下，在碱的存在下，构造一类双核N-融合杂化支架。亲核性加成之后再进行空前的无过渡金属的C（sp 2）-N偶联被认为是该绿色过程的反应途径。

  日期：2024.3.8

  In this study, a synthetic method to access benzo[4,5]imidazo[2,1‐a]isoquinolines is developed by the reaction of 2‐(2‐bromoaryl)benzimidazoles with 1,3‐diketones under basic conditions. A reaction pathway involving the initial formation of a C−C coupled intermediate by nucleophilic aromatic substitution and subsequent deacylative cyclocondensation is proposed for this process.

• Synthesis and toxicity towards normal and cancer cell lines of benzimidazolequinones containing fused aromatic rings and 2-aromatic ring substituents
  作者：Eoin Moriarty、Miriam Carr、Sarah Bonham、Michael P. Carty、Fawaz Aldabbagh

  A facile 6-exo-trig cyclization of sigma-aromatic radicals has allowed the synthesis of various aromatic ring fused benzimidazoles and benzimidazolequinones. The most highly conjugated naphthyl fused benzimidazolequinone, (5-methyl-5,6-dihydrobenzimidazo[2,1-a]benzo[f]isoquinoline-8,11-dione) showed the highest specificity towards human cervical (HeLa) and prostate (DU145) cancer cell lines with little toxicity towards a human normal (GM00637) cell line at doses of <1 mu M. In contrast, 2-aromatic ring substituted (benzimidazole-4,7-diones) analogues, benzimidazolequinone with a pyridine ring and mitomycin C were more toxic than the highly conjugated naphthyl fused benzimidazolequinone towards the normal cell line.
