Abstract
Synthetic routes to pseudo-geminal, pseudo-ortho and ortho hydroxy-oxazolinyl-[2.2]paracyclophanes (and the diastereoisomers of each) for use as N,O ligands in asymmetric catalysis have been devised. The substitution pattern was found to have a strong effect on the rate and enantioselectivity of the formed catalyst in the addition of diethylzinc to benzaldehyde.
