Eight simple N-arylindoles were designed, synthesized and evaluated as human immunodeficiency virus (HIV)-1 integrase inhibitors in vitro for the first time. Among these compounds, 3b, 3e and 3g demonstrated significant anti-HIV-1 integrase activity. Especially 3b showed the highest anti-HIV-1 integrase activity with EC50 value of 7.88 μg/ml and TI value of 24.61. Meantime, some structure–activity relationships were also observed and will provide a new lead for design and discovery of more potent N-arylindoles as HIV-1 integrase inhibitors.

involves the consecutive deprotection of N-arylsulfonylindoles as latent indoles and subsequent S(N)Arreactions with activated aryl halides. This tandemreaction affords an efficient and convenient preparation of N-arylindoles that benefit from prior indoles protection by arylsulfonyl group, and can shorten a reaction sequence and improve synthetic efficiency.

Ullmann-type C-N coupling reaction has been developed for the synthesis of 1-aryl indole derivatives by indoles and aryl halides in the presence of CuI/metformin (CuI/Met) in DMF. This method is very easy, rapid, and high yielding reaction for the synthesis of 1-aryl indoles. In particular, the metformin, which is used as ligand, is inexpensive and nontoxic that is considered to be relatively environmentally benign. (C) 2014 Elsevier Ltd. All rights reserved.

An efficient method for the ultrasound-assisted N-arylation of indoles with haloarenes in an air atmosphere mediated by CS2CO3 without any catalyst is reported. N-arylindoles are obtained in moderate to good yields while indoles cross-coupling with activated aryl halides (X = F or Cl).
