Mukherji, Ananya; Kancharla, Pavan K. published the artcile< C-H···Anion Interactions Assisted Addition of Water to Glycals by Sterically Hindered 2,4,6-Tri-tert-butylpyridinium Hydrochloride>, Quality Control of 4064-06-6, the main research area is pyridinium hydrochloride catalyst stereoselective hydroxylation glycoside preparation glycal; crystal structure steric effect silyl hemiacetal disaccharide glycosylation glycoside.
The conjugate acid of the bulky base 2,4,6-tri-tert-butylpyridine, under mild conditions, catalyzes the synthesis of silyl-protected 2-deoxy-hemiacetals and their dimerized products from glycals at varying concentrations of water. The criticality of the concentration of water in the reaction outcome is indicative of a unique mechanistic pathway for the bulky pyridine salt and not via the general Bronsted acid mechanism. The various silyl-protected hemiacetals thus synthesized were successfully utilized in the stereoselective synthesis of both α and β glycosides.
Organic Letters published new progress about Crystal structure. 4064-06-6 belongs to class alcohols-buliding-blocks, and the molecular formula is C12H20O6, Quality Control of 4064-06-6.
