Nitrene Transfer Catalyzed by a Non-Heme Iron Enzyme and Enhanced by Non-Native Small-Molecule Cofactors [PDF]

open access: yes, 2019
Transition-metal catalysis is a powerful tool for the construction of chemical bonds. Here we show that a non-heme iron enzyme can catalyze olefin aziridination and nitrene C–H insertion, and that these activities can be improved by directed evolution ...

Multifunctional Design of Solid Polymer Electrolytes: Paving the Way for High‐Performance All‐Solid‐State Batteries

open access: yesCarbon Energy, EarlyView.
This review provides a comprehensive and systematic overview of the multifunctional design strategies for solid polymer electrolytes (SPEs), a pivotal component for enabling high‐performance all‐solid‐state batteries (ASSBs). It begins with a detailed classification of SPE systems and elaborates on their respective molecular design principles. The work

Synthetic Strategies for Activity‐Based Probes to Decode Ubiquitin‐Like Modifiers

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT Ubiquitin‐like proteins (Ubls) such as SUMO, NEDD8, ISG15, URM1, UFM1, FAT10, ATG8/ATG12, and FUBI are essential regulators of cellular homeostasis, controlling processes from protein stability and trafficking to immune signaling and autophagy.

Poly(bromoethyl acrylate) : a reactive precursor for the synthesis of functional RAFT materials [PDF]

open access: yes, 2016
Postpolymerization modification has become a powerful tool to create a diversity of functional materials. However, simple nucleophilic substitution reactions on halogenated monomers remains relatively unexplored.

Dual Ligand‐Enabled Nondirected C─H Olefination of (Hetero)Arenes for the Synthesis of Clickable Derivatives

open access: yesChemistry – A European Journal, EarlyView.
We report an efficient method for late‐stage installation of “clickable” alkyne groups into diverse (hetero)arenes. Using a dual‐ligand palladium catalyst that combines an NASA ligand with an N‐heterocycle, an acrylate unit bearing a terminal alkyne can be introduced via nondirected C─H activation.

Concerted [4 + 2] and Stepwise (2 + 2) Cycloadditions of Tetrafluoroethylene with Butadiene: DFT and DLPNO-UCCSD(T) Explorations. [PDF]

open access: yes, 2020
Tetrafluoroethylene and butadiene form the 2 + 2 cycloadduct under kinetic control, but the Diels-Alder cycloadduct is formed under thermodynamic control. Borden and Getty showed that the preference for 2 + 2 cycloaddition is due to the necessity for syn-

Synthesis and Biological Profile of Substituted Pyrrolidinyl Carboxamides for Acyl‐ACP Thioesterase Inhibition

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The work outlined herein covers a series of novel herbicidal lead structures that possess a pyrrolidinyl pyrazole carboxamide scaffold as a key structural feature, carrying further substituted benzyl side chains. Based on scaffold hopping approaches from known fungicidal and herbicidal compounds and utilizing an optimized synthetic approach, a broader ...

Hypervalent Iodine‐Mediated Synthesis of Sulfones Using Organozinc Pivalates and Sulfinate Salts

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A general protocol for sulfone synthesis via sulfonyl‐containing hypervalent iodine reagents and organozinc pivalates is described. The method is practical, provides a broad scope of sulfone in moderate to high yield. bicyclo[1.1.1]pentane‐sulfones are also disclosed and a one‐pot synthesis of Diels–Alder adduct is presented. Sulfones are key motifs in

Aliphatic Poly(Carbonate)s with Acid Responsive Release Mechanisms for Micellar Anti‐Tumor Drug Delivery

open access: yesMacromolecular Rapid Communications, EarlyView.
Micellar systems based on biodegradable aliphatic polycarbonates and acid‐responsive triggers enhance drug solubility, stability, and tumor‐selective release. This review covers micelles with acid‐cleavable drug linkages and those that disassemble via acid‐sensitive functionalities.

Diverse reactivity of maleimides in polymer science and beyond

open access: yesPolymer International, Volume 74, Issue 4, Page 296-306, April 2025.
This mini‐review provides a thorough overview of maleimide chemistry, highlighting its diverse reactivity in polymer and materials science applications. Abstract Maleimides are remarkably versatile functional groups, capable of participating in homo‐ and copolymerizations, Diels–Alder and (photo)cycloadditions, Michael additions, and other reactions ...
