Enantioselective Rh(I)-Catalyzed Cyclization of Arylboron Compounds onto Ketones

Rhodium complexes based upon chiral sulfinamide–alkene, TADDOL-derived phosphoramidite, or diene ligands catalyze cyclizations of arylboron compounds onto ketones, generating a variety of products containing five-, six-, or seven-membered rings with good yields and high enantioselectivities.
