The reaction of enolates derived from titanium and boron complexes of β-hydroxy ketones with aldehydes afforded aldol products in good to excellent yields.Whereas the boron mediated reactions gave exclusively anti aldol products derived from the reaction at Cα, the titanium mediated reactions produced primarily syn aldol products from reaction at Cα'.The product selectivites observed in the titanium mediated aldol reactions were highly dependent on the substitution pattern of the starting β-hydroxy ketone.
