  摘要：

  1-Imidoylbenzotriazoles [N-aryl-1-(1H-benzotriazol-1-yl)-2,2,2-trifluoroethan-1-imines] reacted with tosylmethyl isocyanide according to van Leusen's procedure to give difficultly accessible 1-aryl-4-(4-methylbenzenesulfonyl)-5-(trifluoromethyl)-1H-imidazoles in good yields (81-94%). The initial imidoylbenzotriazoles were conveniently synthesized by reaction of sodium benzotriazolide with the corresponding imidoyl chlorides in THF. The reactions were carried out with a wide series of imidoylbenzotriazoles containing various electron-donating and electron-withdrawing substituents in the N-aryl fragment.

  A new synthetic protocol for the synthesis of 1,4,5-trisubstituted imidazoles containing trifluoromethyl group has been developed using van Leusen reaction, which incorporates two-component condensation reaction trifluoroacetimidoyl chlorides with tosylmethylisocyanide. This protocol provides a novel and improved method for obtaining trifluoromethyl containing 1,4,5-trisubstituted imidazoles in good yields. (C) 2014 Elsevier B.V. All rights reserved.
