HUELGAS, Gabriela et al. Synthesis of New Chiral Monosulfonamides Prepared from (11R,12R)11,12-Diamino-9,10-dihydro-9,10-ethanoanthracene and their Use as Ligands for Asymmetric Catalysis. J. Mex. Chem. Soc [online]. 2013, vol.57, n.1, pp.54-60. ISSN 1870-249X.

New chiral monosulfonamides 6-16 containing (11R,12R)-diamino-9,10-dihydro-9,10-ethanoanthracene as carbon skeleton were prepared. Compounds 6-12, 15 and 16 were used as optically active ligands in the enantioselective ethylation of benzaldehyde. Moreover, the monosulfonamides 6-10 were tested in the asymmetric transfer hydrogenation (ATH) of acetophenone with Rh(Cp*)L* complex.

Keywords : Monosulfonamide; asymmetric catalysis; enantioselective addition.
