Preparation and Catalytic Enantioselective Reactions ofC₃-Symmetric Tris(Oxazoline)s Derived from Kemp's Triacid

Kemp's triacid was elaborated to optically pure tris(β-hydroxylamide)s and tris(oxazoline)s. The resulting C 3-symmetric compounds were used in diethylzinc additions to benzaldehyde and allylic oxidations of cyclopentene, based on Kharash reaction conditions, to give the corresponding products in good chemical yields and moderate enantioselectivities.
