PubMed:Synthesis and conformational analysis of small peptides containing 6-endo-BT(t)L scaffolds as reverse turn mimetics. The preparation of tartaric acids by the oxidation of carbohydrate materials originated in 1860 with Liebig (Annalen, 113, 1) who oxidized lactose with nitric acid to obtain a mixture of dextro- and meso-tartaric acids. Afterwards, you hydrolyze the ester, reforming the pure acid and the alcohol.
