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