  P∗,P∗-Bidentate diastereoisomeric bisdiamidophosphites based on N-benzyltartarimide and their applications in asymmetric catalytic processes

  摘要：

  Two novel P*-stereogenic bisdiamidophosphites derived from (3R,4R)-N-benzyltartarimide as a chiral 1,2-diol have been prepared from readily available starting materials. Palladium and rhodium catalytic systems containing these new P*,P*-bidentate ligands afforded 96%, 83% and 65% ee in asymmetric allylic substitution, hydrogenation and addition processes, respectively. These diastereomeric diamidophosphites were found to be complementary stereoselectors. (C) 2009 Elsevier Ltd. All rights reserved.
