, p. 995 - 1000 (2013/09/23)
A series of glucopyranoside phosphite-pyridine ligands have been applied in the metal-catalyzed allylic substitution and conjugate 1,4-addition reactions of several substrate types. We have been able to identify ligands that provided promising enantioselectivities in the Pd-catalyzed intermolecular allylic substitution of cyclic substrates (ee's up to 86%) and desymmetrization (ee's up to 94%) and in the Cu-catalyzed conjugate addition of challenging aliphatic enones (ee's up to 90%).
