A new approach to the synthesis of Tekturna, a recently marketed drug for hypertension, takes advantage of a modified protocol of the Stoltz palladium-catalyzed asymmetric allylation with a t-BuPHOX ligand for the synthesis of allylated acyclic alkylarylketones. The method led to an α-isopropyl α-allyl arylketone in 90% yield and 88 to 91% ee, which was used in the synthesis of an advanced intermediate
