  Enantioselective rhodium-catalyzed hydrogenation of enol carbamates in the presence of monodentate phosphines

  摘要：

  The rhodium-catalyzed asymmetric hydrogenation of different acyclic and cyclic enol carbarnates to give optically active carbarnates has been examined in the presence of chiral monodentate ligands based on a 4,5-dihydro-3H-dinaphthophosphepine motif 4. The enantioselectivity is largely dependent upon the reaction conditions, the nature of substituents on the phosphorus ligand and structure of the enol carbamate. By applying the optimized reaction conditions, enantioselectivities of up to 96% ee have been achieved. (c) 2007 Elsevier Ltd. All rights reserved.
