✦ Synopsis

Rhodium-catalyzed 1,2-addition of arylboronic acids 4a-j to chiral trifluoroethyl imine 3 afforded diastereomerically enriched sulfinamides 5a-j. The chiral auxiliary of the sulfinamide products was readily removed under acidic methanolysis to provide the corresponding trifluoroethylamine analogs 6a-j.

## 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
