A novel direct and diastereoselective amination of biosourced monobenzylated isohexides has been developed through borrowing hydrogen methodology using a cooperative catalysis between an iridium complex and a phosphoric acid. We also report herein the first regio- and diastereoselective direct amination of isosorbide.
directly functionalized to provide novel amines using the borrowing hydrogen methodology. The efficient regio‐ and diastereo‐controlled synthesis of chiral mono‐ and di‐amines was thus achieved using cooperative catalysis between an iridiumcomplex and a Brønstedacid.
