The amidoalkylation of indoles with N-(α-benzotriazol-1-ylalkyl)amides was smoothly realized with samarium triiodide as a catalyst to give a series of novel 3-indolyl arylmethanamides with good yields and selectivities.

Lewis acid-catalyzed alpha-amidoalkylation of enolizable aldehydes with N-(alpha-benzotriazolyl-alpha-arylalkyl)amides followed by intramolecular Friedel-Crafts cyclization provides a convenient route to 2-substituted 1-amidoindenes.

Various beta '-amido-beta-diketones were first synthesized with N-(alpha-amidoalkyl)benzotriazole-mediated amidoalkylation of 1,3-diketones in moderate yields. These intermediates undergo rapid condensation with hydrazines to give the corresponding N-[beta-(3,5-di and 1,3,5-trisubstituted pyrazol-4-yl)alkyl]amides. (C) 2008 Elsevier Ltd.

N-(1-Benzotriazol-1-ylalkyl)amides 2, easily prepared from an amide and an aldehyde with benzotriazole, react smoothly with CH acids under mild conditions to give the alpha-amidoalkylation products in good yields. Benzotriazole aminals also react with CH acids in the presence of methyl iodide.
