چکیده انگلیسی
Several novel chiral bifunctional l-thiazoline-amide derivatives were simply synthesized from commercially available l-cysteine and l-proline in high yield. These catalysts were subsequently applied to the direct enantioselective aldol reactions of various aldehydes, which are rarely reported in the literature. The products with anti configuration were obtained up to 97% ee and 99% dr when the l-thiazoline-amide derivatives were used. A plausible transition state model was proposed to explain the observed enantio and diastereoselectivities.
