  Synthesis of N-Arylindazoles and Benzimidazoles from a Common Intermediate

  摘要：

  A variety of N-aryl-1H-indazoles and benzimidazoles were synthesized from common arylamino oximes in good to excellent yields The product selectivity depends upon the base used in the reaction, as triethylamine promoted the formation of benzimidazoles, whereas 2-aminopyridine promoted the formation of N-arylindazoles This method is valuable to the synthetic community because both indazoles and benzimidazoles are prevalent in pharmaceuticals

  efficient and facile metal-free, one-pot reaction has been developed to afford diversely substituted N-arylbenzimidazoles through chemoselective in situ generation of N,N′-diarylamidines from arenediazonium salts, nitriles, and free anilines. The advantages of this protocol consist of the operationally easy and simple one-pot procedure under metal-free and mild conditions, the direct use of inexpensive

  An efficient and divergent synthesis of N-arylbenzimidazoles and N-arylindazoles from arylamino oximes based on reaction conditions selection was developed. The synthesis was approached by treating oximes with BTC and the chemoselectivity was regulated by the amount of Et3N. This switchable N-N and N-C bond formation process features mild reaction conditions, simple execution, high chemoselectivity and broad substrate scope. (C) 2020 Elsevier Ltd. All rights reserved.
