Abstract
Chiral diphosphines derived from Diop and BPPM and bearing a phenylcyclohex
ylphosphinogroup and a diphenylphosphinogroup were prepared. These ligands,
and especially the BPPM analog, in association with rhodium complexes, exh
ibited high enantioselectivities, up to 93%, and activities in the reductio
n of various unsaturated substrates although they were used as a mixture 50
/50 of two epimers. (C) 1999 Elsevier Science B.V. All rights reserved.
