Acetoxilación anódica en pequeña y gran escala de compuestos aromáticos

, 2010
The anodic acetoxilation of mesitylene, naphtalene and p-qrmene is studied. In both mesitylene and naphtalene we were interested in a nuclear acetoxilation producís, yeelding after hidrolysis mesitol and alphanaphtol.

Prescribed burning shows minor impacts on black pine needle terpenes and pine processionary moth larval survival

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
Our results highlight that prescribed burning in sub‐Mediterranean pine forests does not affect their resistance to PPM in the short term, either positively or negatively, indicating that it can be implemented to reduce wildfire hazard without influencing forest susceptibility to future PPM outbreaks.

Biomimetic Transformation of p‑Menthene Glucosides into p‑Cymenes and Carvotanacetone

, 2019
A biomimetic transformation of p-menthene glucosides into aromatic monoterpenoids that alluded to mechanisms for essential oil metabolism, which lines up with the precepts of molecular economy, is described. Acid treatment of (−)-(3S,4S,6R)-3,6-dihydroxy-

Drying Method‐Dependent Variations in Phenolics, Color, and Volatile Profile of Thymus praecox subsp. skorpilii

Journal of Food Science, Volume 91, Issue 7, July 2026.
ABSTRACT This study investigated the effects of different drying methods, including freeze drying, oven drying, shade drying, and microwave drying (360, 600, and 900 W), on the volatile profile, total phenolic content (TPC), and color characteristics of wild‐grown Thymus praecox subsp. skorpilii.

Dehydrative Allylic Amination in Water via a Polymer‐Supported Ruthenium Catalyst

ChemSusChem, Volume 19, Issue 12, 26 June 2026.
A green and rapid synthesis of allylamines is achieved using a polymer‐supported ruthenium catalyst. This dehydrative reaction between allyl alcohols and amines proceeds entirely in water without organic solvents or inert gas. The process completes in just 1 h, and the solid catalyst allows for easy filtration, offering a sustainable route to valuable ...

Rh(III)‐Catalyzed [4+2] Annulation of Imidazoles With α‐Diazocarbonyl Compounds: Direct Access to π‐Conjugated Imidazole‐Fused Isoquinolinone

European Journal of Organic Chemistry, Volume 29, Issue 23, 16 June 2026.
A Rh(III)‐catalyzed [4 + 2] annulation of 2‐aryl imidazoles/benzimidazoles with α‐diazocarbonyl compounds is developed for the synthesis of π‐conjugated imidazo/benzimidazo[2,1‐a]isoquinolinones systems. Mechanistic studies and control experiment reveal that the reaction proceeds via imidazole‐directed ortho C(sp2)–H activation, followed by carbene C–H

From Citrus to Cymene: Understanding the Hydrothermal Conversion of Limonene

ChemSusChem, Volume 19, Issue 11, 15 June 2026.
When life gives you limonene… Hydrothermal conversion and pyrolysis of limonene give two distinct sets of products, arising from differing reaction cascades. While p‐cymene dominates in the presence of water, indicative of an isomerisation/aromatisation pathway, pyrolysis favours cracking and loss of carbon affording an m‐xylene rich aromatic mix.

Investigations into the Mechanisms of Zeolite-Catalyzed Transalkylation of iso-Propylbenzene with Toluene

, 2019
The catalytic properties of four large-pore H-beta, Hmordenite, and H-UZM-35) and three medium-pore (H-NU-87, H-TNU-9, and H-ZSM-5) zeolites for the transalkylation of iso-propylbenzene (iPB) with toluene are investigated.

In Vitro Biological Activities of Piper corcovadensis C.DC.: Antioxidant, Antineoplastic‐Related and Antibacterial Effects

The FASEB Journal, Volume 40, Issue 11, 15 June 2026.
Piper corcovadensis extract is rich in bioactive compounds with antioxidant potential, capable of decreasing ROS levels; antitumor activity in cutaneous melanoma cells SK‐MEL‐28; and anti‐inflammatory activity, decreasing the expression of IL‐6 and NLPR3 genes and increasing TNF expression, without cytotoxicity to healthy peripheral blood cells (PBMCs).
