title: Utilization of molybdenum- and palladium-catayzed dynamic kinetic asymmetric transformations for the preparation of tertiary and quaternary stereogenic centers: a concise synthesis of tipranavir.
abstract: Tipranavir, an important antiviral agent in clinical development for the treatment of HIV, is synthesized in 15 linear steps from readily available starting materials in 25% overall yield by utilizing Pd- and Mo-catalyzed DYKAT reactions to control the quaternary and tertiary stereogenic centers, respectively.
