Acyl Amidines by Pd-Catalyzed Aminocarbonylation: One-Pot Cyclizations and ¹¹C Labeling

, 2022
A protocol for the carbonylative synthesis of acyl amidines from aryl halides, amidines, and carbon monoxide catalyzed by Pd(0) is reported herein. Notably, carbon monoxide is generated ex situ from a solid CO source, and several productive palladium ...

Neutrophil extracellular traps induced by activated platelets as a cause of neutrophil–platelet aggregation in β‐thalassaemia/haemoglobin E patients

British Journal of Haematology, EarlyView.
Abnormal neutrophils and platelets in splenectomised β‐thalassaemia/haemoglobin E (HbE) disease contribute to neutrophil–platelet aggregation, leading to a high risk of thrombus formation. Activated platelets induce neutrophils to generate neutrophil extracellular trap (NETs) via the P‐selectin–P‐selectin glycoprotein ligand‐1 (PSGL1) pathway, which ...

An Exploration of Vinamidinium Salts for Frame‐Shifted Synthesis

Israel Journal of Chemistry, Volume 66, Issue 4, July 2026.
Oligoheterocycles are widely used in drug discovery and materials science, where they serve as attractive alternatives to peptide fragments. There is strong interest in understanding the structural correspondence between heterocycles and amino acid motifs to recapitulate key binding elements while improving metabolic stability.

Synthesis of Enantioenriched Primary tert-Butanesulfonimidamides via IminationHydrazinolysis of N-tert-Butanesulfinyl Amidines

, 2022
The first synthesis of primary tert-butanesulfonimidamides with high enantiopurity was realized by imination (or imination/N-functionalization) of enantioenriched N′-tert-butanesulfinyl amidines, followed by hydrazinolysis. N′-Sulfinyl amidines served as
