✦ Synopsis

Lewis bases like phosphines, arsines, and antimonies catalyze the nucleophilic addition of triethylaluminum to epoxides very efficiently. They are proposed to coordinate to triethylaluminum with formation of monomeric and more reactive triethylaluminum Lewis base adducts.

Bidentate phosphites were prepared starting from BINOL, H 8 -BINOL or 3,3%, 5,5%-tetra-tert-butyl-2,2%-biphenol. Utilization of these ligands in the copper-catalyzed enantioselective conjugate addition of triethylaluminum to 2-cyclopentenone afforded 3-ethylcyclopentanone in up to 94.0% ee.
