Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices

Advanced Science, EarlyView.
Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate

1,3-Dipolar cycloadditions of azomethine imines

Organic & Biomolecular Chemistry, 2015
Azomethine imines react with alkenes and alkynes to give pyrazolines, pyrazolidines, pyrazolopyridines, indazoloisoquinolines, pyrazolo[1,5- a ]isoquinolines and pyrazolopyrazolones through regio-, stereo- and enantioselective 1,3-dipolar cycloadditions.

A sequential multistep process for the fully mechanochemical, one-pot synthesis of the antiepileptic drug rufinamide

Green Chemistry Letters and Reviews, 2022
Mechanochemistry is a powerful tool to develop environmentally benign syntheses of active pharmaceutical ingredients. In this context, we report here the synthesis of the anti-epileptic agent rufinamide through a one-pot sequential multi-component ...

(SP,SP)-(–)-(E)-1,2-Bis(methylphenylphosphinoyl)ethene

Acta Crystallographica Section E, 2009
The title compound, C16H18O2P2, possesses two stereogenic P atoms and shows a distorted s–cis conformation of each O=P—C=C moiety. This has been suggested on the basis of the stereochemical result of 1,3-dipolar cycloadditions with ...

The Jekyll and Hyde Nature of Tetrazoles in Polymer Science: From Intrinsic Electronic Duality to Programmable Macromolecular Function

Angewandte Chemie International Edition, EarlyView.
Tetrazoles are reframed as substitution‐programmable heterocycles rather than static functional groups in polymer chemistry. By linking electronic identity to synthetic strategy and polymer architecture, this mini‐review establishes a design framework for translating tetrazole duality into predictable macromolecular function.

Synthesis and Biological Evaluation of Well‐Defined M6P(n)‐Modified Glycopeptides for Targeted Protein Degradation

Chemistry – A European Journal, EarlyView.
A synthetic methodology has been developed to prepare multifunctional M6P and M6Pn ligands of different valency. The glycopeptides were conjugated to cetuximab and then examined to mediate cellular uptake of fluorescently labeled EGFRvIII. Only cetuximab modified by glycopeptides having 3 or 6 M6P or M6Pn residues demonstrated greater uptake.

Coumarin–Tetrapyrrolic Macrocycle Conjugates: Synthesis and Applications

Molecules, 2017
This review covers the synthesis of coumarin–porphyrin, coumarin–phthalocyanine and coumarin–corrole conjugates and their potential applications. While coumarin–phthalocyanine conjugates were obtained almost exclusively by tetramerization of coumarin ...

Synthesis, Physicochemical Characteristics, Self‐Assembly and Encapsulation Ability of per‐Ethylene‐Glycol‐Functionalized Resorcin[4]Arenes and Their Molecular Capsules: On the Road to Liquid Capsules

Chemistry – A European Journal, EarlyView.
Per‐ethylene‐glycol (EG)‐functionalized resorcin[4]arenes containing 12, 16, and 20 EG groups namely compounds 1d, 1e, and 1f, respectively, were prepared and found to self‐assemble, in organic solvents, into hexameric capsules. These capsules are more dynamic than the ones prepared based on alkyl substituted resorcin[4]arenes.

Retro‐Hetero‐Michael Addition Strategies in Organic Synthesis

European Journal of Organic Chemistry, EarlyView.
In this review, synthetic approaches to carbo‐ and heterocyclic compounds, including natural products, published in the last 15 years (2011–2025) which have either relied upon or included a retro‐hetero‐Michael addition step at any stage are discussed.
