Journal ArticleDOI
Glycoside bond formation via acid-base catalysis.
TL;DR: Acid-base catalyzed glycosyl donor and then Glycosyl acceptor activation with phenylboron difluoride or diphenylborons fluoride permits hydrogen bond mediated intramolecular S(N)2-type glycosidation in generally high anomeric selectivity.
Journal ArticleDOI
Synthesis of Glycosylthiols and Reactivity Studies
TL;DR: The acid-catalyzed reaction of 1,2-anhydro-3,4,6-tri-O-benzyl-α-d-glucopyranose as glycosyl donor with bis-trimethylsilyl sulfide as acceptor affords the α-thiol, which should provide with O-glycosyl trichloroacetimidates as Glycosyl donors that have nonparticipating groups at C-2.
Journal ArticleDOI
Iodine catalyzed one-pot diamination of glycals with chloramine-T: a new approach to 2-amino-β-glycosylamines for applications in N-glycopeptide synthesis
Vipin Kumar,Namakkal G. Ramesh +1 more
TL;DR: Iodine catalyzes a facile one-pot direct diamination of glycals with chloramine-T to afford stereoselectively 2-amino-beta-glycosylamine derivatives that serve as convenient precursors for the synthesis of N-linked glycopeptides.
Journal ArticleDOI
A versatile strategy for the synthesis of N-linked glycoamino acids from glycals.
Vipin Kumar,Namakkal G. Ramesh +1 more
TL;DR: A versatile route for the synthesis of N-linked glycoamino acids from readily available glycals is reported and an illustrative synthesis of an N- linked glycopeptide 29 is also reported.
Compritrol ATO 888 based solid lipid nanoparticles of cefixime: Formulation and evaluation
TL;DR: Results showed that cefixime absorption is enhanced by using solid lipid nanoparticles formulations and the relative bioavailability of cefIXime-SLNs was found to be 1.87%.
