The asymmetric hydrogenation of 1-aryl-2-imidazol-1-yl-ethanones offers a concise route to homochiral 1-aryl-2-imidazol-1-yl-ethanols. Catalytic asymmetric transfer hydrogenation with formic acid using [( R, R )-TsDPEN]Ru(Cymene)Cl as precatalyst was shown to be effective in this transformation. Pre...
