摘要：
The whole "pybox" and dice: Highly enantioselective amination reactions of both allylic and benzylic C-H bonds are catalyzed by cationic ruthenium(II)-pybox complexes (see structure). A novel mode of stereocontrol, which is induced by the versatile pybox ligand, is proposed to account for the excellent enantioselectivity in these reactions. Boc = tert-butoxycarbonyl, pybox = pyridine bisoxazoline. (Chemical Equation Presented) © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
