Enantioselective organocatalytic aryloxylation of β-keto esters
An efficient enantioselective aryloxylation of cyclic β-keto esters with a selection of substituted o-quinones catalyzed by a bifunctional cinchona alkaloid derivative, giving entry to tricyclic dioxin adducts with high enantio- and diastereoselectivity, is described. Georg Thieme Verlag Stuttgart - New York.
