Aplicação

L-(+)-Tartaric acid may be used in the synthesis of (R,R)-1,2-diammoniumcyclohexane mono-(+)-tartrate, an intermediate to prepare an enantioselective epoxidation catalyst.[1] It may also be used as a starting material in the multi-step synthesis of 1,4-di-O-benzyl-L-threitol.[2] It can be used a chiral resolving agent for the resolution of 2,2′-bispyrrolidine.[3]

Chiral building block for natural products.[4] Also forms a Diels-Alder catalyst with TiCl₂(O-i-Pr)₂.[5]
