(+)-Di-tert-butyl L-tartrate（Cat No.:M027437）is a chiral diester derived from naturally occurring L-tartaric acid, featuring two bulky tert-butyl ester groups. This compound is widely used as a chiral auxiliary or ligand in asymmetric synthesis, especially in the preparation of enantioselective catalysts and resolution of racemic mixtures. Its rigid, stereochemically defined backbone allows for precise control over stereochemical outcomes in organic transformations. It is particularly valuable in Sharpless asymmetric epoxidation and related catalytic systems. Stable and easy to handle, it plays a crucial role in the synthesis of optically pure pharmaceuticals and fine chemicals.
