supporting information; experimental part, p. 6448 - 6451 (2009/03/11)
(Chemical Equation Presented) Skip the chiral ligand: A chiral Lewis acid strategy for effecting asymmetric induction in oxidative systems not amenable to strongly binding chiral ligands is disclosed and its mechanism investigated. The highest levels of enantioselectivity for allylic C-H oxidation of terminal olefins is reported (see scheme; BQ=1,4-benzoquinone, LA=chiral Lewis acid).

We are reporting a mild, chemo-, and highly regioselective Pd(II)-catalyzed allylic oxidation of α-olefins to furnish branched allylic esters that proceeds via a novel serial ligand catalysis mechanism in which two different ligands (i.e., vinyl sulfoxide 2 and BQ) interact sequentially with the metal to promote distinct steps of the catalytic cycle (i.e., C-H cleavage and π-allyl functionalization, respectively).
