摘要：
C-Alkylation at the active methylene group of 2-phenacyl-1H-benzimidazoles with phenacyl bromides proceeds highly selectively with the formation of the corresponding 1,4-diketones, which on heating with hydrochloric acid are cyclized with the formation of the previously unknown 2-(2,5-diaryl-3-furyl)-1H- benzimidazoles. © 2007 Springer Science+Business Media, Inc.
