Abstract
AbstractA 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 chromenones proceeds smoothly in up to 70 % yield with up to 95 % ee.
