Other Bisphosphane Ligands

This chapter describes atropisomeric biaryl bisphosphine ligands modified DIOP-type ligands P-chiral bisphosphane ligands other bisphosphane ligands and their applications in the enantioselective hydrogenation of olefins. 

Some other efficient chiral bisphosphane ligands have been listed in Figure 8. Those include Achiwa s BPPM,125 and a series of modified BPPM ligands such as BCPM and MOD-BPPM 126,126a 126j some excellent chiral... 

In 2011, Nadeau and coworkers [27] developed the first rhodium-catalyzed asymmetric arylation of N-benzyl nicotinate stJts (other C=N double bond substrates) with arylboronic acids. The use of an axial chiral bisphosphane ligand (i )-CTH-P-Phos gave a variety of six-substituted dihydropy-ridines with excellent enantioselectivities (Scheme 6.22). The usefulness of the method lies on the facile conversion of the dihydropyridines into the synthetically useful piperidines.
