Chemische Eigenschaften
Colorless to light yellow liqui
Chemische Eigenschaften
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.
Verwenden
(+)-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.
Verwenden
(+)-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.
Verwenden
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.
Allgemeine Beschreibung
Made from natural tartaric acid
