Mild Conditions. -A new chiral bis-phosphine ligand with a paracyclophane backbone is prepared and used as ligand in Rh-catalyzed hydrogenations of dehydroamino acid esters such as (I) with high enantioselectivity. -(PYE, P.
## Abstract A new chiral aminophosphine ligand 6,6β²βdimethoxyβ2,2β²βbis(diphenylphosphinoamino) biphenyl (DMBDPPABP) was prepared and its rhodium complex was found to be an effective catalyst for the asymmetric hydrogenation of amidoacrylic add and its derivatives. The effects of solvent and reactio
