Palladium-based Kinetic Resolution of Racemic Tosylaziridines

Dicationic Pd(II) complexes with chiral pyridine bis(oxazoline) ligands are catalysts for kinetic resolution of racemic styrene tosylazirdines. Treatment of styrene tosylaziridine with 0.5 equivalents of alcohol in the presence of the chiral Pd catalyst affords β-alkoxy tosylamide with ee up to 71%.
