with thiosulfonates. The in situ aldolreaction of these compounds with ethyl acetateenolate is highlystereoselective (1,2-asymmetric induction) and yields diastereomeric mixtures of β-hydroxyesters (the configuration of the major one being dependent on the sulfenylating agent) that can be readily separated and transformed into the enantiomerically pure title ketones.
