## Abstract A new family of benzene‐based chiral heterodisulfoxide ligands **L1**–**L5** was synthesized in a single step. These disulfoxide ligands were applied in the rhodium‐catalyzed asymmetric 1,4‐addition of arylboronic acids to chromenones. The addition of diverse arylboronic acids to chrome
