An efficient method is described for the synthesis of N-(2-aminophenyl)-2-hydroxyethylamines via a copper catalyzed N-selective arylation of beta-amino alcohols with iodoanilines. The corresponding coupling products are useful intermediates for the synthesis of a variety of N-2-hydroxyethyl-substituted benzimidazoles, benzimidazolones, and iminobenzimidazoles. We found that 2-iodoaniline only arylates certain amino alcohols but not amines lacking a hydroxyl group. We also demonstrate the arylation of sterically demanding beta-amino alcohols, such as ephedrine and prolinol with aryl iodides at room temperature. (C) 2013 Elsevier Ltd. All rights reserved.

The regio- and stereospecific conversion of syn- and anti-1,2-amino alcohols to their respective syn- and anti-1,2-imidazolylpropylamines via treatment with 1,1‘-carbonyldiimidazole is described. The rationale behind the regio- and stereospecific nature as well as the generality of the reaction is discussed.
