Cp*RhIII/Chiral Disulfonate/CuOAc Catalyst
System for the Enantioselective Intramolecular Oxyamination of Alkenes
Posted on 2021-12-07 - 18:33
The
enantioselective intramolecular oxyamination of unsaturated
alkoxyamines using a hybrid catalytic system consisting of Cp*RhIII/chiral disulfonate/CuOAc is described. Tetrahydrofuran
derivatives with a tetrasubstituted chiral center were obtained under
the optimized conditions in 91:9–97:3 er. The use of a sterically
hindered chiral disulfonate and a Cu additive was essential for the
high enantioselectivity.
