F. Touchard et al., THIOUREAS - NEW LIGANDS FOR THE METAL-CATALYZED ASYMMETRIC REDUCTION OF CARBONYL-COMPOUNDS, Tetrahedron : asymmetry, 8(19), 1997, pp. 3319-3326
The catalytic enantioselective hydride transfer reduction of prochiral
ketones using differently substituted mono and dithioureas with sever
al catalyst precursors is reported. The best results are obtained with
a ruthenium complex and a C-2 symmetric ligand. (C) 1997 Elsevier Sci
