Ligand exchange of titanium(IV) alkoxides with alpha-hydroxy acids presents an unexpected and novel approach to enantioselective aldol additions of aldehydes and ketones. The aldol products were isolated in a high degree of syn-diastereoselectivity. High enantioselectivities were observed by using simple optically pure alpha-hydroxy acids in this novel aldol addition.
