Nonconventional Techniques in Plant Alkaloid Extraction: A Decade of Progress (2014–2023)

Chemistry &Biodiversity, EarlyView.
This figure seeks to represent the evolution of the different unconventional approaches that were adopted for the extraction of plant‐derived alkaloids during the decade from 2014 to 2023. ABSTRACT Plant metabolism encompasses primary and secondary pathways, with secondary metabolism yielding diverse natural products crucial for plant adaptation and ...

Cannabinoids From Trema micranthum (L.) Blume (Cannabaceae): A Cannabinoid Profiling System

Chemistry &Biodiversity, EarlyView.
ABSTRACT Trema micranthum (L.) Blume is a species from the Cannabaceae botanical family, present all over the tropics. A recent study conducted by our group identified the presence of cannabidiol (CBD), Δ9‐tetrahydrocannabinol, cannabidiolic acid, and tetrahydrocannabinolic acid‐A in T. micranthum extracts.

Advances in Ligand‐Driven Pd‐Catalyzed C─H Functionalizations: Recent Insights and Updates

ChemCatChem, EarlyView.
The most significant advances in ligand‐driven Pd‐catalyzed organic synthesis over the past two years are presented. Processes involving C─H activation of substrates, avoiding their prefunctionalization are illustrated. Both the activity and selectivity of the catalyst depend on the design of the ligands (pyridones, pyridines, amino acids, phosphines ...

Sensory properties of menthol and smoking topography

Tobacco Induced Diseases, 2011
Although there is a great deal known about menthol as a flavoring agent in foods and confections, less is known about the particular sensory properties of menthol cigarette smoke.

Palladium‐Catalyzed Telomerization of Isoprene with Amines: Ligands and Solvents Working Together to Improve the Selectivity

ChemCatChem, EarlyView.
Palladium‐catalyzed telomerization of isoprene with diethylamine using non‐protic solvents and phosphite ligands with large cone angle afforded telomer 3 (T–T) in up to 90% yield and 90% selectivity. Phosphite ligands with small cone angle provided telomer 4 (H‐T) with selectivity of 43% (80% yield) and 48% (23% yield) with iPr2NH.

Visible Light‐Induced N‐Heterocyclic Nitrenium‐Catalyzed Deoxygenative Borylation of Acyl Chlorides

ChemistryEurope, EarlyView.
Herein, direct deoxygenative borylation of acyl chlorides is reported, which is an unknown but desirable chemical transformation. The N‐heterocyclic nitrenium ion has been utilized as the photocatalyst under mild reaction conditions to synthesize a series of alkylboronates using bis‐(catecholato)diboron (B2cat2) as the diboron reagent.

Molecular mechanisms underlying menthol binding and activation of TRPM8 ion channel

Nature Communications, 2020
Menthol in mints elicits a coolness sensation by selective activation of TRPM8 ion channel. Here authors dock menthol to TRPM8 and systematically validate their menthol binding models with thermodynamic mutant cycle analysis in functional tests, and shed

Local sensitivity analysis of a supercritical extraction model

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the process of chamomile oil extraction from chamomile flowers. A parameter‐distributed model, consisting of a set of partial differential equations, was used to describe the governing mass transfer phenomena between solid and fluid phases under supercritical conditions using carbon dioxide as the solvent.
