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. All rights reserved.
