Aplicaciones

(+)-Diethyl L-tartrate is used as a chiral auxiliary in the Sharpless enantioselective epoxidation of allylic alcohols, for Sharpless-type enantioselective oxidation of sulfides to sulfoxides and as a chiral auxiliary in the enantioselective construction of cyclopropanes from allylic alcohols by an asymmetric Simmons-Smith reaction. It is also used as a chiral reagent in a host of chemical reactions, such as the synthesis of isoquinoline alkaloids and arundic acid, which has been used in acute ischemic stroke therapy.

Notas

Keep container tightly sealed. Store in cool, dry conditions in well sealed containers. Incompatible with oxidizing agents.
