(+)- tartaric acid or dextrotartaric acid. The mirror-image (enantiomeric) form, levotartaric acid or D-(?)-tartaric acid, and the achiral form, mesotartaric acid, can be made artificially. The dextro and levo prefixes are not related to the D/L configuration (which is derived rather ...
DL-Tartaric acid is a water- and alcohol-soluble colorless crystalline solid with a characteristic acid taste and a melting temperature of 170°C(338°F). Naturally occurring tartaric acid is generally of the L-configuration (based on the absolute configuration of D-glyceric acid). The L-forms...
Method of resolving bicyclic imino-&agr;-carboxylic acid ester racemates The invention relates to a process for resolving racemic mixtures of bicyclic imino-&agr;-carboxylic acid esters into the components of the formula Ia and Ib ##STR1## in which R.sup.1 stands for an aliphatic, cycloaliph...
An efficient strategy to synthesize tartaric acid building blocks for totally regioselective transformations or derivatizations was disclosed. Starting from l-tartaric acid or l-dimethyl tartrate, respectively, we obtained type I and II building blocks with orthogonal sets of protecing groups (4-8 step...

The Raman optical activity spectra of (2 R, 3 R) (+)- and (2 S,3 S) ()-tartaric acid, (2 R, 3 R) (+)-dimethyl tartrate, (2 R,3 R) ()-2,3-butanediol and (2 S, 3 S) (+)-dibenzoyl tartaric acid are presented. A large couplet at about 500cm 1 in the first three...
C: control; A: tartaric acid added; SA: steam + tartaric acid added; S: steam. As for experimental samples, the impact of different treatments (S, SA, and A) was evident, showing a significant reduction in AA concentrations. The introduction of steam (S samples) during the baking ...
-tartaric acid, and the achiral form, mesotartaric acid, can be made artificially. The dextro and levo prefixes are not related to the D/L configuration (which is derived rather indirectly[8] from their structural relation to D- or L-glyceraldehyde), but to the orientation of the optical ...
