N-Tosyl-(Sa)-binam-L-prolinamide is an efficientcatalyst for the aqueousaldolreaction, between glyoxylic acid, as monohydrate or aqueous solution, and ketones. This reaction led to the formation of chiral α-hydroxy-γ-keto carboxylic acids in high levels of diastereo- and enantioselectivities achieving mainly anti aldol products.
