of substrates, employs commercially available or readily attainable reagents, tolerates sensitive functionality on both partners, and affords the product ketoacids in moderate to high yields. The use of a chiral phosphinooxazoline results in a desymmetrization of a meso anhydride to provide the ketoacid in 85% yield and 79% ee.
