Abstract
The rhodium-catalyzed asymmetric hydrogenation of acylaminocinnamic ac id esters, bearing different protective groups. has been investigated in the presence of PROPPAPHOS, BPPM, DIOP, and Ph-beta-GLUP as chiral ligands. The influence of the protective group on the rate and enantio selectivity of the hydrogenation is described.
