  Enantioselective Rh-Catalyzed Hydrogenation of 3-Aryl-4-phosphonobutenoates with a P-Stereogenic BoPhoz-Type Ligand

  摘要：

  A series of chiral 3-aryl-4-phosphonobutyric acid esters were synthesized in high enantioselectivities (93-98% ee) via the Rh-catalyzed asymmetric hydrogenation of the corresponding 3-aryl-4-phosphonobutenoates using a P-stereogenic BoPhoz-type phosphine-aminophosphine ligand. The methodology has been successfully applied to the asymmetric synthesis of a potential GABA(B) antagonist, (R)-phaclofen, in high enantioselectivity.

  The asymmetric conjugate reduction of 3-aryl-4-phosphonobutenoates has been demonstrated which provides an enantioselective synthesis of optically active 3-aryl-4-phosphonobutyric acid esters. A wide range of 3-aryl-4-phosphonobutenoate derivates are reduced with high enantioselectivities (up to 94% ee) using an (S)-Segphos/Cu(OAc)(2)center dot H2O catalyst system (1 or 5 mol %) in the presence of PMHS and t-BuOH. The reduction is influenced by the steric and electronic effects of the substrates. (C) 2012 Elsevier Ltd. All rights reserved.
