Are the FelkinβAhn and Cram chelate models reliable? These models predict asymmetric induction without consideration of solvent and temperature. However, the addition of __n__βbutyllithium to the __N__β(trimethylsily)imine of (2__S__)βlactal leads to __syn/anti__ ratios between 98:2 and 28:72 when p
