Chelation‐Assisted Metal‐Catalyzed Ligation and Cleavage Reactions for Chemical Biology

European Journal of Organic Chemistry, EarlyView.
Chelation‐assisted transition metal catalysis has emerged as a promising complement to bioorthogonal click chemistry for studying biological processes. By pre‐organizing catalytic metal centers, designed coordinating substrates enhance reactivity and biocompatibility, enabling site‐selective ligation and decaging reactions in complex biological media ...

Selective N‐Functionalization of Pyrazoles

European Journal of Organic Chemistry, EarlyView.
This review traces the evolution of regioselective N‐functionalization strategies for pyrazoles, a key class of nitrogen heterocycles widely used in medicinal chemistry. Due to rapid tautomerism, N‐functionalization often lacks selectivity, leading to poor and unpredictable regioisomeric outcomes.

Efficient Synthesis of Cannabinoid Acids

European Journal of Organic Chemistry, EarlyView.
In this study, an alternative synthesis of cannabinoid acids was developed based on an O→C acyl rearrangement. Specifically, this strategy involved regioselective bromination followed by halogen–lithium exchange and intramolecular nucleophilic addition, which led to successful carboxylation.

Optimising the Eco‐Friendly Extraction of Carotenoids From Gac Fruit: A Sustainable Solution for Natural Red Food Colourants

Food Chemistry International, EarlyView.
Gac fruit's high carotenoid content, especially in the aril, makes it an excellent natural red pigment source for food applications, offering a safer alternative to synthetic dyes. Ethanol extraction achieved the highest overall pigment recovery (89.53%), whereas ethyl lactate extraction yielded the highest levels of total carotenoids, β‐carotene ...
