Reduction of Nitroarenes into Aryl Amines and N-Aryl hydroxylamines via Activation of NaBH4 and Ammonia-Borane Complexes by Ag/TiO2 Catalyst

Nanomaterials, 2016
In this study, we report the fabrication of mesoporous assemblies of silver and TiO2 nanoparticles (Ag/MTA) and demonstrate their catalytic efficiency for the selective reduction of nitroarenes. The Ag/TiO2 assemblies, which show large surface areas (119–

Examining the effects of additives and precursors on the reactivity of rhodium alkyl nitrenes generated from substituted hydroxylamines

Frontiers in Chemistry, 2023
In this study, the reactivity of the alkyl nitrenes, generated from the substituted hydroxylamine precursors, was determined using the same rhodium catalyst. The results revealed that in competitive C–H insertion experiments, the regioselectivity between

-Propargylic Hydroxylamines via a Tandem Rearrangement-Cyclisation Reaction [PDF]

, 2006
A method for the conversion of O-propargylic hydroxylamines into 2-isoxazolines in 60-84% yield is described. For 3-alkylpropargyl or 3-arylpropargyl hydroxylamines this was achieved by heating a methanolic solution of the hydrochloride salt in the ...

Synthesis of densely functionalized enantiopure indolizidines by ring-closing metathesis (RCM) of hydroxylamines from carbohydrate-derived nitrones

Beilstein Journal of Organic Chemistry, 2007
BackgroundIndolizidine alkaloids widely occur in nature and display interesting biological activity. This is the reason for which their total synthesis as well as the synthesis of non-natural analogues still attracts the attention of many research groups.

Indium-Mediated Reduction of Hydroxylamines to Amines [PDF]

, 2016
A novel and simple procedure for reduction of hydroxylamines to the corresponding amines by means of indium powder in aqueous media is reported. Applicability to one-pot reactions and isoxazolidine N−O bond reduction is also demonstrated.

Cyclic azapeptide CD36 ligand attenuates cardiac injury and reduces long‐chain fatty acid accumulation after myocardial ischemia–reperfusion in mice

FEBS Open Bio, EarlyView.
In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.

Clusterization‐Triggered Emission from Cellulose‐Based Luminophores in Dilute Aqueous Solution through Imine Formation

Advanced Functional Materials, EarlyView.
Clusterization‐triggered emission is realized in dilute aqueous solution by introducing imine linkages into cellulose‐based luminophores. Imine functionalization creates O/N‐rich, hydrogen‐bonded clustered microenvironments that stabilize emissive states and restrict molecular motions. Luminescence is tunable by amine type and multiplicity.
