Palladium Catalyzed Asymmetric Hydrophosphination of Internal Alkynes: Access to Phosphine-Functionalized Axially Chiral Olefins
Palladium-catalyzed unprecedented atroposelective hydrophosphination of sterically hindered internal alkynes with secondary phosphines has been realized, affording C-N axially chiral trisubstituted olefins (vinylphosphines) in {excellent|superb|outstanding|exceptional|great|fantastic} regioselectivity, (E)-selectivity, and enantioselectivity. The axial…
