Polycyclic Aromatics as Promising Phosphorescence Materials

open access: yesChemistryEurope, EarlyView.
This review focuses on the recent progress of polycyclic aromatic compounds (PACs)‐based phosphorescent materials. Their molecular structural characteristics as promising phosphors are highlighted, and the efficient strategies from molecular and aggregation levels have been illustrated systematically to promote the development of PACs with desirable ...

Catalytic SuFEx Reactivity of Sulfonimidoyl Fluorides with Functionalized Amines with Automation Applicable Conditions

open access: yesChemistryEurope, EarlyView.
GA: Sulfonimidoyl fluorides react with a diverse set of amines in a HOBt‐catalyzed sulfur(VI) fluorine exchange reaction to access sulfonimidamides, including directly NH‐sulfonimidamides, and in an automated workflow. In addition, SNAr reactivity of 4‐fluoroaryl sulfonimidoyl fluorides is discovered and exploited to prepare complex sulfonimidoyl ...

Preparation of Enantioenriched Spirocyclic Scaffolds Transferring Axial Chirality from Borylalkylidenecycloalkanes

open access: yesChemistryEurope, EarlyView.
Enantiomerically enriched borylalkylidenecycloalkanes can transfer axial chirality to spirocyclic compounds with central chirality, without erosion of enantiomeric ratio. The method involves cyclopropanation, borylcyclopropanation, epoxidation, and aziridination reactions, that proceed in astereodivergent manner giving access to spirocycles with ...

Tricyclic mappings: revisited

open access: yesFixed Point Theory and Algorithms for Sciences and Engineering
In order to study the existence of best proximity points of a ( T ) $\left ( T\right ) $ condition satisfying mapping, we introduce a new interesting notion of triangular projection in geodesic metric spaces. Using the famous Schauder fixed point theorem,

CuH‐Catalyzed Asymmetric Desymmetrization of Cyclobutenes via Stereodivergent Hydroamination

open access: yesChemistryEurope, EarlyView.
The CuH‐catalyzed stereodivergent hydroamination through asymmetric desymmetrization of cyclobutenes has been achieved, yielding a range of trisubstituted aminocyclobutanes with excellent results. A series of subsequent transformations, including the first asymmetric synthesis of two pharmaceutically active molecules, have been realized, and density ...

Experimental pharmacological research regarding the antidepressant effect of associating doxepin and selegiline in normal mice [PDF]

open access: yes, 2019
The severity and complexity of depression can vary widely among individuals, thus making single drug therapy ineffective in some cases. Taking this fact into account and using a mouse model, we set on investigating the possibility of obtaining a ...

Synthesis and Evaluation of DNA Cross‐linkers by Click Chemistry‐Mediated Heterodimerization of Nor‐Tomaymycins

open access: yesChemistry – A European Journal, EarlyView.
Click chemistry promises a simple method to produce pyrrolo[2,1‐c][1,4]benzodiazepine (PBD)‐based DNA binders. DNA binding and covalent crosslinking capabilities have been validated for ‘clicked’ PBD heterodimers using thermal denaturation analysis, mass spectrometry and DNase I footprinting.
