摘要

While N-(2-nitrobenzylidene) anilines produced mixtures of 2, 1-benzisoxazoles and 3- anilino-2-aryl-2H-indazoles in the presence of indium and iodine in MeOH, N-(2- nitrobenzylidene) anilines were transformed into 3-anilino-2-aryl-2H-indazoles as the predominant major product through the change of the solvent from protic MeOH to aprotic THF. In an indium-mediated one-pot reductive reaction, 2-benzaldehydes and anilines in ...
