资源简介：
A palladium-catalyzed asymmetric
[3 + 2] annulation reaction between
racemic 5-vinyloxazolidinones and N-sulfonyl imines
was established. Under the influence of the palladium complex with
a chiral ammonium-phosphine hybrid ligand, the cycloaddition proceeded
smoothly to yield imidazolidines bearing α-amino quaternary
stereocenters in high yields with excellent diastereo- and enantioselectivities.
