  Swift and Efficient Synthesis of 4-Phenylquinazolines: Involvement of N-Heterocyclic Carbene in the Key Cyclization Step

  摘要：

  An original route to 2-alkyamino-4-phenylquinazolines in three steps from simple (hetero)aromatic amines is reported here. The key step involves the intramolecular cyclization of benzoyl arylguanidines performed in [OMIm]Cl ionic liquid. The basic (hetero)aromatic guanidines deprotonate the imidazolium-based Ionic liquid, thus triggering the cascade process ultimately leading to the intramolecular cyclization. This reaction is the first example of a Friedel-Crafts-type reaction in which an N-heterocyclic carbene is involved in the formation of the electrophilic intermediate.

• Copper-Catalyzed Domino Three-Component Approach for the Assembly of 2-Aminated Benzimidazoles and Quinazolines

  A copper-promoted three-component synthesis of 2-aminobenzimidazoles (1) or of 2-aminoquinazolines (2) involving cyanamides, arylboronic acids, and amines has been developed. The operationally simple oxidative process, performed in the presence of K2CO3, a catalytic amount of CuCl2·2H2O, 2,2′-bipyridine, and an O2 atmosphere (1 atm), allows the rapid assembly of either benzimidazoles or quinazolines

  已经开发了一种铜促进的三组分合成2-氨基苯并咪唑（1）或2-氨基喹唑啉（2）的方法，该方法涉及氰胺，芳基硼酸和胺。在K 2 CO 3，催化量的CuCl 2 ·2H 2 O，2,2'-联吡啶和O 2气氛（1个大气压）的存在下进行的操作简单的氧化过程可以使任何一种的快速组装分别从芳基或苄基取代的氰胺开始的苯并咪唑或喹唑啉。在这个过程中，铜促进了三个键，两个C–N键以及一个由CH–H功能化事件产生的额外键的形成。

  Diarylcarbodiimides or benzylphenylcarbodiimides are converted to 1,2-disubstituted benzimidazoles or 1,2-disustituted quinazolines via addition/intramolecular CH bond activation/C-N or CC bond forming reaction using copper(II) acetate/oxygen [Cu(OAc)2/O2] as the oxidant at 100 °C in one-pot cascade procedure.
