Late-stage fluorination of bridged scaffolds: chemoselective generation of a CHF group at three positions of the bicyclo[3.3.1]nonane system [PDF]

, 2018
Monofluorobicyclo[3.3.1]nonane derivatives were prepared by late-stage fluorination, often proceeding with control of stereochemistry. Introduction of fluorine at the 3-, 6- or 7-position was achieved chemoselectively, the bicyclo system being ...

Non‐Dilute Synthesis of Macrodiolides and Macrotetrolides Enabled by Confinement Catalysis

Angewandte Chemie, Volume 138, Issue 34, 17 August 2026.
Confinement catalysis within a hexameric resorcin[4]arene capsule enables macrolactonization under non‐dilute conditions (up to 0.1 M), overcoming the limitations of high‐dilution protocols (0.1–10 mM). This strategy provides direct access to 18–32‐membered macrodiolides and 26–32‐membered macrotetrolides in one pot and unlocks previously inaccessible ...

Spectroscopic and In Silico Determination of the Structural and Antioxidant Properties of Essential Oils From Lavandula Species Cultivated in the Silivri Region of Istanbul

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Plants are important sources of bioactive compounds that contribute to nutrition, health maintenance, and disease prevention. In this study, the chemical composition and antioxidant potential of essential oils obtained from Lavandula angustifolia “Sevtopolis” and Lavandula × intermedia cultivated in the Silivri region of Istanbul were ...

Synthesis of polysubstituted oxygenated bicyclo compounds [PDF]

, 2019
Saturated (or at least sp3-enriched) molecules have acquired an increasingly important role in medicinal and organic chemistry. The architectural complexity of three-dimensional, saturated molecules often confers greater biological activity and makes ...

Mass Spectrometry for Semiquantitative Analysis of Thermal Decomposition: A Methodological Case Study on the Pyrolysis of a (CH3)SiO1.5 Hybrid Gel

Rapid Communications in Mass Spectrometry, Volume 40, Issue 21, 15 November 2026.
ABSTRACT Rationale The thermal decomposition of (CH3)SiO1.5 gels has been systematically investigated by TG‐MS, revealing a complex temperature‐dependent evolution of gaseous species. This work demonstrates that the TG‐MS analysis, coupled with rigorous data processing, allows to set up an insightful methodology to evolve from a qualitative monitoring ...

Alkoxyallenes in Modern Synthesis: Reactivity, Catalysis, and Complexity Generation

Advanced Synthesis &Catalysis, Volume 368, Issue 17, 1 September 2026.
The last decade has witnessed a remarkable transformation in alkoxyallene chemistry. Although historically employed as synthetic equivalents of acrolein or as versatile 3C synthons, alkoxyallenes are now increasingly recognized as highly adaptable platforms for synthetic design.
