Further improvement on sulfonamide-based ligand for catalytic asymmetric 2-haloallylation and allylation.
The sulfonamide-based ligand B was found to exhibit an outstanding crystallinity and perform well as a ligand for Cr-mediated catalytic asymmetric 2-haloallylation and allylation. The new ligand has an appealing advantage over the first generation ligand; its high crystallinity allows effective recovery of the ligand from a reaction in a pure form.
