Enantioselective Amination of Benzylic and Allylic C-H Bonds

The catalytic formation of C-N bonds via insertion reactions has been extensively studied [dirhodium(II) complexes, manganese- and ruthenium-porphyrin complexes, etc.]. Based on previously reported work in the field, a new and efficient catalytic system of pyridine bisoxazoline dirhodium(II) complex is developed and applied to the asymmetric amination of benzylic and allylic C-H bonds of sulfamate esters.
