A Solvent‐Free Synthesis of Imidazo[1,5‐a]pyridines Using CCl4 as an Oxidant

open access: yesJournal of Heterocyclic Chemistry, EarlyView.
A solvent‐free synthesis of imidazo[1,5‐a]pyridines (Impys) using CCl4 as an oxidant reagent and DBU as the base is informed. An array of Impys derived from different benzylic, heteroaryl aldehydes and others was synthesized in moderate to good yields.

Enrichment of Hyaluronic Acid Binding Tumor Cells by Modulation of Selective Adhesion on Microgel Surfaces

open access: yesMacromolecular Rapid Communications, EarlyView.
We have developed a thermoresponsive microgel system for the selective enrichment of hyaluronic acid‐binding tumor cells. By modulating the adhesion on the microgel surface via temperature changes from 37°C to 30°C, we demonstrate a novel proof‐of‐principle for separating these tumor cell from white blood cells, which has potential applications in ...

The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

A Versatile Heterometallic Microporous MOF for Photocatalytic Hydrogen Generation

open access: yesSmall, EarlyView.
This work describes a green and scalable approach to robust and flexible heterometallic MOFs, MIP‐215's, with tunable photoactivity for efficient, noble‐metal‐free solar hydrogen production. ABSTRACT Photocatalytic particulate systems offer a cost‐effective solar hydrogen production but are generally limited by narrow visiblelight absorption and poor ...

Visible‐light‐promoted catalyst‐free benzylic C‐H oxidation using molecular oxygen as a green oxidant

open access: yesSmart Molecules, EarlyView.
A green and simple photo‐oxygenation of benzylic C‐H bond with molecular oxygen was developed for the preparation of a series of carbonyl compounds. The straightforward C‐H carbonylation strategy features catalyst‐ and additive‐free reaction conditions, only oxygen as a green oxidant, broad scope and scalable, and the simple‐operation nature.

Dimethyl‐, Diethyl‐, and Propylene Carbonates: An Emerging Class of Green Solvents for Organic Synthesis

open access: yesThe Chemical Record, EarlyView.
This review highlights recent advances in the use of organic carbonates, dimethyl carbonate (DMC), diethyl carbonate (DEC), and propylene carbonate (PC), as solvents in organic synthesis. Based on over seventy studies from the past 6 years, it shows their application in different organic reaction types, emphasizing their role in safer and more ...
