Synthesis and Evaluation of Antimicrobial Activity of Nitrones from Derivatives of Aryl-Substituted Dihydroisoquinoline

open access: yesJournal of Chemistry, 2015
This paper describes the synthesis of a series of dihydroisoquinoline nitrones by isomerization of the corresponding oxaziridines. Nitrones 4a–c were obtained in excellent yields and high purity by a simple and effective method from the isomerization of ...

Molecular Networks in Dynamic Multilevel Systems [PDF]

open access: yes, 2018
Dynamic multilevel systems can be assembled from molecular building blocks through two or more reversible reactions that form covalent bonds. Molecular networks of dynamic multilevel systems can exhibit different connectivities between nodes.

(4+2)-cycloaddition of nitroalkenes with ynamines; formation of a 4H-1,2-oxazine 2-oxide derivative [PDF]

open access: yes, 1980
The formation of a thermally unstable (4+2)-cycloadduct, a 4H-1,2-oxazine 2-oxide derivative ( ), from the reaction of 1-nitrocyclopentene with 1-phenyl-2-(1-pyrrolidinyl)acetylene has been proven by the structure elucidation of isoxazole derivative ...

A Straightforward Route to Enantiopure Pyrrolizidines and Indolizidines by Cycloaddition to Pyrroline N-Oxides Derived from the Chiral Pool

open access: yesMolecules, 1998
Enantiomerically pure, five membered cyclic nitrones, easily obtained in large amounts from protected hydroxyacids and aminoacids such as D- and L-tartaric, L-malic, and L-aspartic acids, give cycloaddition reactions with a good diastereocontrol.

Crystal structure and Hirshfeld surface analysis of N-[(Z)-(2-hydroxyphenyl)methylidene]aniline N-oxide

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2021
The conformation of the title compound, C13H11NO2, is partially determined by a strong, intramolecular O—H...O hydrogen bond. The crystal packing consists of strongly corrugated layers parallel to the ac plane and associated through C—H...π(ring ...

Easy Access to Configurationally Controlled C-Glycofuranoside-Based Building Blocks by Means of Formyl C-Glycofuranosides [PDF]

open access: yes, 2010
A general approach to enantiopure C-glycofuranoside-based hybridα/β-amino acids and nitrones, among other valuable building blocks, has been established via formyl C-glycofuranosides, easily available from hexose-derived equatorial-2-OH-glycopyranosides ...

Synthesis of a New β-Galactosidase Inhibitor Displaying Pharmacological Chaperone Properties for GM1 Gangliosidosis

open access: yesMolecules, 2022
GM1 gangliosidosis is a rare lysosomal disease caused by the deficiency of the enzyme β-galactosidase (β-Gal; GLB1; E.C. 3.2.1.23), responsible for the hydrolysis of terminal β-galactosyl residues from GM1 ganglioside, glycoproteins, and ...

Cycloaddition of Benzyne with Alkoxy-Substituted Pyrroline-N-oxides­: Unexpected Rearrangement to an N-Phenylpyrrole

open access: yesSynOpen, 2018
Reaction of enantiopure 3,4-dialkoxy-pyrroline N-oxides with benzyne affords the expected tetrahydrobenzo[d]pyrrolo[1,2-b]isoxazoles along with an unexpected 2,3-disubstitued-N-phenyl-pyrrole derived from an unprecedented rearrangement of the adduct of ...
