摘要

Abstract The preparation and preliminary biological evaluation of the (2-cycloalkyl-1- benzimidazolyl)-N, N-diethylacetamides 7a–e are described. Key steps for the preparation of the compounds 7a–d are (i) the homolytic cycloalkylation of benzimidazole, in which the silver-catalyzed oxidative decarboxylation of the cycloalkanecarboxylic acids 1a–d by peroxydisulfate is used as a source of alkyl radicals, and (ii) the N-alkylation of ...
