SmI2‐Catalyzed Coupling of Alkyl Housane Ketones and Alkenes in an Approach to Norbornanes

open access: yesAngewandte Chemie, Volume 137, Issue 39, September 22, 2025.
Samarium diiodide (Sml2) is an effective catalyst for the mild, atom‐economical coupling of bicyclo[2.1.0]pentane, or housane, ketones, and electron‐deficient alkenes to give functionalized norbornane structural motifs not easily accessible by classical cycloaddition approaches.

Hydrogen Peroxide‐Responsive Aminoferrocene Prodrugs

open access: yesEuropean Journal of Organic Chemistry, Volume 28, Issue 33, September 20, 2025.
To improve sensitivity toward H2O2, the boronic acid pinacol ester in known aminoferrocene‐based anticancer prodrug 13b is replaced with an α‐ketamide fragment to obtain prodrug 2a and some of its N‐alkylated derivatives. 2a exhibits substantially improved cytotoxicity in vitro toward ovarian cancer A2780 and Burkitt's lymphoma BL‐2 cells.

Fluorinated tranylcypromine analogues as inhibitors of lysine-specific demethylase 1 (LSD1, KDM1A) [PDF]

open access: yes, 2017
We report a series of tranylcypromine analogues containing a fluorine in the cyclopropyl ring. A number of compounds with additional m- or p- substitution of the aryl ring were micromolar inhibitors of the LSD1 enzyme.

Synthesis of retro-inverso peptides employing isocyanates of Nα-Fmoc-amino acids/peptide acids catalyzed by DMAP [PDF]

open access: yes, 2006
The Goldschmidt-Wick type reaction between isocyanates of Nα-Fmoc-amino acids/peptide acids and Nα-Boc-/Z-/Bsmoc-amino acids catalyzed by DMAP leads to the incorporation of a reversed peptide bond.

Synthesis of New N,N′‐Diarylureas and Their Theoretical Study as Cannabinoid‐1 Receptor Inhibitors

open access: yesChemPlusChem, Volume 90, Issue 8, August 2025.
A series of new pyrazolo‐ and triazolo‐based N,N′‐diarylureas is synthesized following the triphosgene protocol in the last step. Density functional theory calculations and molecular docking provide strong evidence that all new compounds bind strongly to the cannabinoid‐1 (CB‐1) receptor, showing comparable results with the known allosteric CB‐1 ...
