Synthesis of novel chiral bisoxazoline ligands with a norbornadiene backbone: use in the copper-catalyzed enantioselective Henry reaction

Trang Linh 297 14 pdf

Novel chiral bisoxazoline ligands based on norbornadiene were synthesized and used for the asymmetric Henry reaction. Various aromatic aldehydes were converted into chiral β -nitro alcohols with high yields and moderate to acceptable enantioselectivities under the optimized reaction conditions. The short and efficient synthesis of bisoxazoline ligands, the flexibility in ligand design, coordination to a large number of transition metals, and excellent enantioselectivity in many reactions make these ligands indispensable in asymmetric catalysis. |
