Vicinal diones and α-keto esters are demonstrated to be electrophiles of both natural and computationally designed aldolases with various catalytic mechanisms, facilitating efficient asymmetric synthesis of small molecules with tertiaryalcohols.

Novel primary–tertiary diamine organocatalysts derived from l-serine were utilized to promote enantioselective aldolreaction of acetone with α-ketoesters. The desired products were obtained in high yields and with good to excellent enantioselectivities (up to 95% ee).
