Pyridinyloxazolidines: versatile scaffolds for chiral catalyst construction

Pyridinyloxazolidines are structurally versatile chiral ligand frameworks that are easily made and coordinated to Pd(II); the resulting complexes, which show significant steric and electronic differences from their oxazoline counterparts, as well as intermolecular H-bonding in the solid state, can be isolated in diastereomerically pure form and are remarkably resistant to hydrolysis.
