Description and Uses
(+)-Dimethyl L-tartrate can react with sulfur tetrafluoride to form dimethyl meso-2,3-difluorosuccinate.
It may be used in the synthesis of the following chiral ligands for use in asymmetric synthesis:
- (2R, 3R)-1,4-dimethoxy-1,1,4,4-tetraphenyl-2,3-butanediol
- (-)-(4S,5R)-4-(2-pyridyl)-5-(diphenylphosphino)methyl-2,2-dimethyl-1,3-dioxolane (PYDIPHOS)
- (4R,5R)-α,α,α′,α′-2,2-hexaphenyl-4,5-dimethanol-1,3-dioxolane
