Abstract
Systematic study of the transition metal-catalyzed aldol reactions of certain prochiral ketones with methyl isocyanoacetate has been made. H igh diastereoselectivity (80-98% de) of these condensations, leading t o methyl -dihydro-5,5-(disubstituted)-4-oxazolecarboxylates was shown to be controlled by the nature of both catalyst and substituents on th e starting ketone.
