A document type is Article, introducing its new discovery.
Chiral macrocyclic CrIII salen complexes have been synthesized, characterized, and used as catalysts in the asymmetric aminolysis of aromatic ester epoxides with various anilines to prepare the beta-amino-alpha-hydroxyl esters in very good yield (up to 95 %) along with high diastereo- and enantioselectivity (dr>99/1, ee up to 96 %) under the optimized condition particularly with CrIII complex 4, which was effectively recycled four times.
