摘要
A new series of modular chiral selenium-containing oxazolines has been synthesized from inexpensive and commercially available L-serine and L-aspartic acid. These new compounds were evaluated as chiral ligands in the palladium-catalyzed asymmetric allylic alkylation reaction, furnishing the product in high enantiomeric excess, using CS2CO3/CH2Cl2 as the base/solvent system.
