Allylic azide rearrangement in tandem with intramolecular Huisgen cycloaddition for iminosugar and glycomimetic synthesis. Functionalized piperidine, pyrrolidine and pyrrolotriazoles from D-mannose
(Thieme Publishing, 2017-04-20)
Intramolecular Huisgen azide-alkene cycloaddition reaction of 7-azido-hepta-1,5-diene-3,4-diols, prepared from methyl α-d-mannopyranoside, were carried out. Allylic azide rearrangement to secondary azides occurred ...
A comprehensive spectroscopic study of the polymorphs of diflunisal and their phase transformations
Understanding phase transitions in pharmaceutical materials is of vital importance for drug manufacturing, processing and storage. In this paper we have carried out comprehensive high-resolution spectroscopic studies on ...
A comprehensive cocrystal screening study of chlorothiazide
(American Chemical Society, 2017-09-01)
Cocrystal formation of chlorothiazide (ctz) was screened with a variety of coformers with carboxyl, amide, hydroxyl, sulfonamide, pyridine, amidine, and amine functional groups. New cocrystals with acetamide (aca), benzamide ...
Stereoselective epimerizations of glycosyl thiols
(American Chemical Society, 2017-10-17)
Glycosyl thiols are widely used in stereoselective S-glycoside synthesis. Their epimerization from 1,2-trans to 1,2-cis thiols (e.g., equatorial to axial epimerization in thioglucopyranose) was attained using TiCl4, while ...
