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]
