The intermolecular reductive coupling of aromatic imines with acylimidazoles was effected by electroreduction in the presence of chlorotrimethylsilane and gave a-amino-a-aryl ketones. This method was also effective for the synthesis of alpha-amino-alpha-aryl esters using methoxycarbonylimidazole as an electrophile. (c) 2007 Elsevier Ltd. All rights reserved.

An effective redox deracemization of α-aryl glycine esters has been described. The one-pot redox process consisted of copper(II) catalysis using molecular oxygen as terminal oxidant and chiral phosphoric acid catalyzed asymmetric transfer hydrogenation with benzothiazoline as hydride donor. The reaction exhibited good functional group tolerance, providing a range of optically active non-natural α-aryl
