Synthesis and X-ray crystallographic investigation of N-(3-deoxy-3-acetamido-β-D-glycopyranosyl)alkanamides as analogs of N-glycoprotein linkage region
TLDR
Comparative analysis of the synthesis and X-ray crystal structures of N-(3-deoxy-3-acetamido-β-D-glycopyranosyl)acetamide and the corresponding propionamide showed that the bifurcated anti-parallel pattern involving N–H…O and C–H….O hydrogen bonds is absent in both the C3 acetamido analogs. Expand
Zeolite catalyzed selective deprotection of di- and tri-O-isopropylidene sugar acetals.
H-Beta zeolite, a microporous solid acid, is demonstrated to be an efficient catalyst for the selective deprotection of cyclic as well as acyclic O-isopropylidene sugar acetals derived fromExpand
Synthesis and characterization of thiourea- and urea-linked glycolipids as low-molecular-weight hydrogelators
Novel glycolipids with thiourea- and urea-linkers have been synthesized as low-molecular-weight gelators by reacting glycosyl aminoacetamides with alkyl isothiocyanates and isocyanates. The influenceExpand
Synthesis of N-(β-D-glycuronopyranosyl)alkanamides and 1-(β-D-glycuronopyranosyl)-4-phenyl-[1,2,3]-triazoles as N-glycoprotein linkage region analogs: examination of the effect of C5 substituent on
TLDR
Uronic acid alkanamides and triazole derivatives have been designed and synthesized as newer analogs of N-glycoprotein linkage region to understand the influence of the carboxylic group on linkage region torsion as well as on molecular packing. Expand
Synthesis and X-ray crystallographic investigation of N-(β-D-glycosyl)butanamides derived from GlcNAc and chitobiose as analogs of the conserved chitobiosylasparagine linkage of N-glycoproteins.
TLDR
This is the first report on the crystal structure analysis of chitobiosyl alkanamide as analog of the N-glycoprotein linkage region, (GlcNAcβ(1-4)Glc NAc)βAsn, and this orientation was found to be almost similar to β-N,N'-diacetylchitobiose trihydrate. Expand
Effect of distal sugars and interglycosidic linkage on the N-glycoprotein linkage region conformation: synthesis and X-Ray crystallographic investigation of β-1-N-alkanamide derivatives of cellobiose
TLDR
The present finding explicitly proved the importance of molecular architecture in the N-glycoproteins linkage region to maintain the linearity, planarity and rigidity that are necessary for N- glycan to serve role in inter- as well as intramolecular carbohydrate-protein interactions. Expand
Synthesis and characterization of thiourea- and urea- linked glycolipids as low-molecular-weight
Novel glycolipids with thiourea- and urea-linkers have been synthesized as low-molecular-weight gelators by reacting glycosyl aminoacetamides with alkyl isothiocyanates and isocyanates. The influenceExpand
Thiourea linked glycolipid-assisted synthesis of sub-micrometer sized polyaniline spheres for enzyme less sensing of dopamine
A simple methodology of synthesizing sub-micrometer sized polyaniline (PANI) spheres using gold electrodes with thiourea linked glycolipid self-assembly for the selective detection of dopamine (DA)Expand
Synthesis of N‐Protected/Free Indole‐7‐Carboxaldehyde
Abstract A direct method for the preparation of N‐protected/free indole‐7‐carboxaldehyde is reported from the corresponding N‐protected 7‐bromomethylindoles using three different conditions.
