TCI B6639 2,2'-Bis[(4S)-4-benzyl-2-oxazoline] (CAS 133463-88-4) is a C2-symmetric chiral bis(oxazoline) — or BOX — ligand available from AMI Scientific. Complexed with transition metals such as copper, zinc, magnesium, or palladium, it creates a well-defined chiral pocket that delivers high enantioselectivity. Typical uses include asymmetric cyclopropanation, aldol and Michael additions, and chiral Lewis acid Diels-Alder reactions. Supplied in 200 mg and 1 g research packs, it should be kept tightly sealed in a cool, dry, moisture-free environment for reliable catalytic performance.
