Bicyclic Bridgehead Phosphoramidite (Briphos) Ligands with Tunable π‑Acceptor Ability and Catalytic Activity in the Rhodium-Catalyzed Conjugate Additions
A new type of bicyclic bridgehead
phosphoramidites (briphos) is
reported, where the geometrical constraints significantly enhance
the π-acceptor ability compared with its monocyclic analogs.
The briphos is shown to be highly efficient and tunable for RhÂ(I)-catalyzed
conjugate additions of aryl boronic acids to α,β-unsaturated
ketones and <i>N</i>-tosyl ketimines
