Here we show that simple and readily available chiral sulfinamide-olefins can display great catalytic activities and enantioselectivities in rhodium-catalyzed 1,4-addition reactions. This study represent the first example of chiral sulfur-based olefin ligand class for transition metal-catalyzed asymmetric transformation.
Design of N-cinnamyl sulfinamides as new sulfur-containing olefin ligands for asymmetric catalysis: achieving structural simplicity with a categorical linear framework
The design and development of an extraordinarily interesting new class of chiral sulfur–olefin hybrid ligands with remarkable structural simplicity were described. These unique sulfinamide–olefin ligands have been proved to be highly effective ligands in rhodium-catalyzedasymmetric1,4-addition reactions of arylboronicacids to α,β-unsaturated carbonyl compounds (up to 99% yield and 98% ee).
