| | L(+)-Diethyl L-tartrate Usage And Synthesis |
| Chemical Properties | Colorless to light yellow liqui | | Chemical Properties | Diethyl tartrate has a mild, fruity, wine aroma. | | Occurrence | The d-isomer has not been reported found in nature; the l-isomer and the racemic form are of little importance.
Reported found in sherry, white and red wine. | | Uses | (+)-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. | | Uses | Diethyl L-(+)-Tartrate is 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 thera
py. | | Uses | (+)-Diethyl L-tartrate can be used in the synthesis of biologically active compounds such as (+)-altholactone, (-)-aspicilin, (+)-monomorine I and (+)-(1R,2R,3S,6S)-3,6-di-O-methyl conduritol-E. | | General Description | Made from natural tartaric acid | | Flammability and Explosibility | Non flammable |
