资源简介：
A highly enantioselective rhodium-catalyzed arylation of cyclic diketimines with arylboronic acids was achieved under mild conditions by employing a simple, sulfinamide-based branched olefin ligand. This protocol provides an efficient access to valuable chiral tetrasubstituted 1,2,5-thiadiazoline 1,1-dioxides in high yields with excellent enantioselectivities of up to 99% ee.
