Chiral sulfonated phosphines. VIII. Hydrogenation of dehydropeptides in a two-phase system
Laghmari, M.,Sinou, D.,Masdeu, A.,Claver, C.
, p. 213 - 216 (2007/10/02)
Dehydropeptides have been reduced in a two-phase system using 2> associated with chiral water-soluble ligands derived from cyclobutanediop and BDPP.Diastereoselectivities of up to 87percent were obtained with tetrasulfonated BDPP.

ASYMMETRIC HYDROGENATION OF DEHYDRODIPEPTIDES WITH RHODIUM(I)-CHIRAL DIPHOSPHINITES. SELECTIVE (S,S)- AND (R,R)-PRODUCT FORMATION BY DOUBLE ASYMMETRIC INDUCTION.
Yatagai,Yamagishi,Hida
, p. 823 - 826 (2007/10/02)
In the hydrogenation of dehydrodipeptides, the effect of chiral center of the substrate ((S) or (R)) on the asymmetric induction was examined using the catalysts of Rh(I)-chiral diphosphinite containing pyrrolidine moiety (POP). The catalysts with POP's h
