Aminohydroxy phosphine oxide ligands in ruthenium-catalysed asymmetric transfer hydrogenation reactions
摘要:
A class of aminohydroxy phosphine oxide ligands was derived from optically active amino alcohols, containing stereogenic centres at phosphorus and at carbon. Their activities and selectivities in the asymmetric transfer hydrogenation reaction were assessed, including match and mismatch of chiralities. Enantioselectivities of more than 92% were achieved in the reduction of acetophenone and propiophenone under mild reaction conditions. (C) 2004 Elsevier Ltd. All rights reserved.
