2.3- Dihydroxysuccinic acid

Tartaric acid [526-83-0] (2,3-dihydroxybutanedioic acid, 2,3-dihydroxysuccinic acid), C H O, is a dihydroxy dicarboxyhc acid with two chiral centers. It exists as the dextro- and levorotatory acid the meso form (which is inactive owing to internal compensation), and the racemic mixture (which is commonly known as racemic acid). The commercial product in the United States is the natural, dextrorotatory form, (R-R, R )-tartaric acid (L(+)-tartaric acid) [87-69-4]. This enantiomer occurs in grapes as its acid potassium salt (cream of tartar). In the fermentation of wine (qv), this salt forms deposits in the vats free crystallized tartaric acid was first obtained from such fermentation residues by Scheele in 1769. [Pg.524]

Tartaric (2,3-dihydroxysuccinic) acid is an important representative of dihydroxydicarboxylic (aldaric) acids and the most prominent acid in wine. In nature it occurs almost exclusively as (-l-)-L-tartaric acid (8-66), also known as dextrotartaric acid or L-threaric acid, which is (2J ,3J )-isomer. Occasionally tartaric acid occurs as (-)-tartaric, laevotartaric acid, which is the (2S,3S)-isomer, also known as D-threaric acid (8-66). An optically inactive racemic mixture of both isomers, called racemic (uvic) acid, has been demonstrated in grape juice, the optically active symmetric (2J ,3S)-tartaric acid (8-66) called meso-tartaric or erythraric acid does not occur in nature. Synthetic racemic and meso-tartaric acids are used as acidulants. [Pg.561]

Waanders et al. (714) started the synthesis of (-)-aspicilin from 2R,3R-dihydroxysuccinic acid and 2-propyne-l-ol as shown in Scheme 44. Solladie et al. (662) synthesized (-)-aspicilin by condensation of triphenylphosponium iodide 44 with aldehyde 45 prepared from C-3/C-9 fragment 46 (see Scheme 45). The C-3/C-9 fragment was synthesized via two different routes (661, 68a) (see Schemes 46a and 46b). [Pg.43]
