[reaction: see text] A new strategy to control the enantioselectivity of Lewis acid catalyzed reactions has been investigated. The use of N-acryloyl-1,3-benzoxazol-2-(3H)-ones substituted at position 4 leads to the formation of diastereomeric complexes as a result of the presence of a chiral axis. The stereochemical outcome of the reaction is controlled by the chiral catalyst and by the chiral axis
