A Systematic Review of Synthetic and Anticancer and Antimicrobial Activity of Quinazoline/Quinazolin‐4‐one Analogues

ChemistryOpen, EarlyView.
Quinazoline represents an important class of heterocycles with diverse medicinal and pharmacological significance. This review systematically examines scholarly efforts toward understanding different synthetic pathways emphasizing the role of metal and non‐metal catalysts including some miscellaneous reagents employed in the synthesis of quinazoline ...

The Copolymerization Performance of 2‐Cyclopropyl‐2‐Oxazoline and 2‐Cyclopropyl‐2‐Oxazine Contributes to Tunable Temperature‐Responsive (Co)Polymer Characteristics

Journal of Polymer Science, EarlyView.
Using the cationic ring‐opening polymerization method: homopolymers and heteropolymers with tailored temperature response are generated from 2‐cyclopropyl‐2‐oxazoline and 2‐cyclopropyl‐2‐oxazine. The strategy allows for maintaining the same side chains and addressing the influence of the ring size of the cyclic imino ether regarding its kinetics and ...

The continuing significance of chiral agrochemicals

Pest 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.
