New chiral diamino ligands as sparteine analogues. Application to the palladium-catalyzed kinetic oxidative resolution of 1-phenyl ethanol

Novel chiral 9-keto-bispidines were investigated as ligands in the palladium-catalyzed kinetic oxidative resolution (KOR) of 1-phenyl ethanol. The ligands were easily prepared by means of a two-step synthetic sequence starting from commercially available products.
