Synthesis of α-amino amidines through molecular iodine-catalyzed three-component coupling of isocyanides, aldehydes and amines

Beilstein Journal of Organic Chemistry, 2014
A facile and efficient synthetic protocol for the synthesis of α-amino amidines has been developed using a molecular iodine-catalyzed three-component coupling reaction of isocyanides, amines, and aldehydes. The presented strategy offers the advantages of

Electrochemical Dehydration of Carboxamides to Their Nitriles

European Journal of Organic Chemistry, Volume 29, Issue 10, 9 March 2026.
Electrochemical dehydration of carboxamides to nitriles is achieved using thiocyanate‐mediated activation, avoiding stoichiometric reagents. In an undivided cell at ambient conditions, 18 aromatic and aliphatic substrates give good‐to‐excellent yields (up to 84%) with functional‐group tolerance. Cyclic voltammetry supports an EC‐type‐mediated oxidation.

An Amidinate‐Stabilized Germatrisilacyclobutadiene Ylide

Chemistry – A European Journal, 2012
AbstractThe synthesis and characterization of new amidinate‐stabilized germatrisilacyclobutadiene ylides [L3Si3GeL′] (L=PhC(NtBu)2; L′=ËL; Ë=Ge (3), Si (7)) are described. Compound 3 was prepared by the reaction of [LSiSiL] (1) with one equivalent of [LGeGeL] (2) in THF. Compound 7 was synthesized by the reaction of 2 with excess 1 in THF.

ROS Activated NETosis of Bone Marrow CD55+ Intermediate Mature Neutrophils Through HIF1α‐PADI4 Pathway to Initiate Bone Aging

Advanced Science, Volume 13, Issue 16, 18 March 2026.
In this study, we find CD55+ neutrophils show activated NETosis within bone marrow, induce BMSC senescence and osteogenesis inhibition, finally leading to bone aging initiation. Mechanistically, ROS synergizes with the CD55‐driven HIF1α‐PADI4 pathway to promote NETosis.
