Abstract: The newly developed chiral ligands 1 and 4 show opposite enantioselectivity in the asymmetric reduction of prochiral ketones resulting in the production of either enantiomer depending on the metal complex with high enantiomeric excess.

Keywords: Oxazaborolidines; dihydrooxazaborins; oxazaaluminium complex; Chiral switch
