Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

open access: yesChemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

1,3-Difunctionalization of [1.1.1]propellane through iron-hydride catalyzed hydropyridylation

open access: yesNature Communications
Current methodologies for the functionalization of [1.1.1]propellane primarily focus on achieving 1, 3-difunctionalized bicyclo[1.1.1]pentane or ring-opened cyclobutane moiety. Herein, we report an innovative approach for the 1, 3-difunctionalization of [

Mechanisms and Clinical Manifestations of Age‐Related Impairment in Wound Healing

open access: yesInternational Wound Journal, Volume 23, Issue 7, July 2026.
ABSTRACT Chronic wounds account for a considerable burden on the overall US healthcare system, affecting an estimated 10.2 million people and costing as much as $148 billion dollars in 2022 alone. Elderly patients suffer disproportionately, as nearly 85% of the chronic wound population is over the age of 65 years old.

Investigation of 222‐nm ultraviolet C irradiation bactericidal effect on the surgical field in a rabbit model

open access: yesPhotochemistry and Photobiology, Volume 102, Issue 4, Page 845-853, July/August 2026.
In a rabbit surgical field model seeded with polymicrobial flora, a single dose of 222‐nm UV‐C (500 mJ/cm2) markedly reduced bacterial colonies, achieving a bactericidal effect comparable to 254‐nm UV‐C (200 mJ/cm2), while no UV‐C irradiation showed heavy growth. Wound healing did not differ among groups. Microbiota profiling detected SSI‐relevant taxa

SYNTHESIS OF CYCLOBUTANE ANALOGUES

open access: yesBulletin of the Chemical Society of Ethiopia, 2009
2-(3-Acetyl-2,2-dimethylcyclobutyl)acetic acid (pinonic acid) was synthesized using α-pinene as raw material and potassium permanganate as oxidant. This compound reacted with substituted aniline to produce eight kinds of derivatives with cyclobutane moiety. The yields of the cyclobutane analogues ranged from 24.9 to 78.2 %. KEY WORDS: Cyclobutane
