Abstract

AbstractA type of optically pure secondary‐amino aromatic Tf‐amide organocatalysts can be easily prepared from commercially available L‐hydroxyproline. The chemical behavior of these organocatalysts was investigated by the application to asymmetric aldol reactions. Among these, catalyst 2 a efficiently catalyzed direct asymmetric aldol reactions of cycloalkanones and substituted benzaldehydes, which afforded the corresponding aldol adducts in good yield with good to excellent anti‐diastereo and enantioselectivity.
