Rh-ImiFerroPhos complexes catalyzed asymmetric hydrogenation of β-substituted α,β-unsaturated hosphonates

A range of optically active β-substituted alkylphosphonates have been prepared in good yields and good enantioselectivity under mild conditions via the Rh-catalyzed asymmetric hydrogenation of β-substituted α,β-unsaturated phosphonates using chiral ImiFerroPhos ligands.
