Utilizing the I\_-valine-based chiral lithioenamine (5) of ethyl acetoacetate (l), enantioface differentiating Michael reaction with alkylidenemalonates (2) gave, after decarboxylation, B-substituted g-keto esters (3) in a fair to good enantiomeric excess. Kinetic diastereoenrichment of the initial
