Abstract
Enantiomerically pure diamino-bis (tert-thiophene) 1b proved to be a valuable and flexible chiral ligand for Pd-and Zn-catalyzed transformations, allowing for high levels of stereocontrol in asymmetric allylic alkylation (ee up to 99%) and hydrosilylations of prochiral carbonyls (ee up to 97%).
