A one-pot method for the synthesis of 2-aminobenzimidazoles and related heterocycles

A rapid and efficient one-pot method for the synthesis of 2-aminobenzimidazoles and related heterocycles is described. The reaction is mediated by a polymer-supported carbodiimide, which simplifies product isolation. The scope and limitations of this method are described. (c) 2006 Elsevier Ltd. All rights reserved.
