Novel sulfamide−amine alcohol ligands were designed using a grafting strategy and synthesized from readily available starting materials via a simple, efficient method. The key features of these ligands for the asymmetric addition of diethylzinc to aldehydes included stability, enhanced effectiveness without using Ti(OiPr)4, suitability for a variety of aldehydes, the ability to operate at room temperature
