    Description

    Application

    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.[7] It may also be used as a starting material in the multi-step synthesis of 1,4-di-O-benzyl-L-threitol.[8] It can be used a chiral resolving agent for the resolution of 2,2′-bispyrrolidine.[9]

    Chiral building block for natural products.[1] Also forms a Diels-Alder catalyst with TiCl2(O-i-Pr)2.[2]
