摘要
A practical synthesis of potentially tridentate P,N,N-ligands containing two stereogenic elements incorporated into the axially chiral Quinazolinap and centrally chiral 2-oxazoline subunits is reported. The application of these novel hybrid ligands in Pd(0)-catalyzed asymmetric allylic alkylation revealed the matched and mismatched diastereomer, dominant stereogenic element, as well as the effect of the oxazoline R substituent on the level of enantioselectivity (ee's up to 81%).
