Abstract
HUELGAS, Gabriela; QUINTERO, Leticia and ANAYA DE PARRODI, Cecilia. Enantioselective Addition of Et2Zn to Benzaldehyde Activated by Benzamides Containing the (S)-α-Phenylethyl Group. J. Mex. Chem. Soc [online]. 2007, vol.51, n.4, pp.249-251. ISSN 1870-249X.
Application of atropisomeric ligands, i.e. 2-aminobenzamides 1a-e and 2-sulfonamidobenzamides 2a-e, in the addition of Et2Zn to benzaldehyde afforded low to moderate enantioselectivities (up to 63% ee).
Keywords : atropisomers; benzamides; chiral ligands; diethylzinc; enantioselective addition.
