As mentioned earlier, the structures of tartaric acid are given above. In comparison with an enantiomer, the differences in the structure of all three compounds are apparent. A. A chiral molecule with an asymmetric carbon B. An achiral molecule with a carbon molecule, which is not asymmetrical...
Bijvoet (1951) first utilized this anomaly to determine the absolute configuration of the dextrorotatory (+)-tartaric acid in the form of its sodium-rubidium salt, using ZrKα radiation. (By good luck, this coincided with Fischer's notation.) Today, it is possible to determine reliably the ...
1,4-Dimethylpiperazine di-betaine (DBPZ) forms a crystalline complex with l-tartaric acid (TA) and two and a half water molecules. The crystals are monoclinic, space group P2 1. The piperazine has a chair conformation with the methyl groups in the equatorial positions and the axial CH 2COO...

摘要: Two series of symmetry-based HIV protease inhibitors containing (S,S) or (R,R) tartaric acid core structure were prepared and tested for inhibitory property against the enzyme. All compounds showed weak antiprotease activity.关键词: HIV-1 protease inhibitors, with (S,S) or (R,R) ...
In later work Pasteur discovered a fourth species of tartaric acid [if we count the enantiomers A and B and the racemate (A + B) as three distinct species]. He was not able to explain the nature of this optically inactive isomer, but the Le Bel–van't Hoff theory led to assignment ...

(+)-tartaric acid in the form of its sodium-rubidium salt, using ZrKαradiation. (By good luck, this coincided with Fischer's notation.) Today, it is possible to determine reliably the absolute configuration of a medium-sized molecule containing one atom of phosphorus or a heavier element,...
