Synthesis of Cyclic Derivatives of Tartaric Acid by Condensing Alkyld-Tartrates with Aromatic Aldehydes. (Optical Activity and Chemical Structure in Tartaric Acid. VI)

Diastereoselective encapsulation of tartaric acid by a helical aromatic oligoamide.

A helical aromatic oligoamide foldamer encapsulates tartaric acid with exceptional affinity, selectivity, and diastereoselectivity. The structure of the complex has been elucidated both in solution by NMR spectroscopy and in the solid state by X-ray crystallography, making it possible to rationalize the strong effects observed, particularly the role of hydrogen bonds between the hydroxyl and ca...

Tartaric Acid Dehydrogenase Activity in Higher Plants1,2

Although the tartrates have been considered as possible metabolites in higher plants since the initial work of Pasteur in 1848, surprisingly little is known of their actual physiological significance. Vickery and Palmer (35) have briefly reviewed the history of (+)-tartrate in plants, including the problems of identification and of nomenclature. They conclude that (+)-tartrate is an uncommon pl...

Stereoselective radical reactions of some tartaric and glyceric acid derivatives.

[reaction: see text] Free radicals generated by the decarboxylation of dimethoxydioxanecarboxylic acids derived from L-(+)-tartaric acid and L-glyceric acid added to some maleimides and acrylates with high stereoselectivity. This method provides easy access to some chiral building blocks.

Significance of urinary tartaric acid.

L-tartaric acid synthesis from vitamin C in higher plants.

The biosynthetic pathway of L-tartaric acid, the form most commonly encountered in nature, and its catabolic ties to vitamin C, remain a challenge to plant scientists. Vitamin C and L-tartaric acid are plant-derived metabolites with intrinsic human value. In contrast to most fruits during development, grapes accumulate L-tartaric acid, which remains within the berry throughout ripening. Berry t...
