Harnessing Carbenoid Reactivity From Imidazoles and Oxiranes
Advanced Synthesis &Catalysis, Volume 368, Issue 4, 17 February 2026.The combination of azole compounds and oxiranes exhibits carbenoid reactivity at elevated temperatures, as demonstrated by the successful benzoin condensation of aromatic aldehydes. Using this catalytic system to polymerize bifunctional aldehyde/oxirane monomers yields thermosets with glass transition temperatures above 100°C.

PdII‐Mediated Oxidative Amination for Access to a 9‐Azabicyclo[4.2.1]nonane Compound Library and Anatoxin‐a [PDF]
European Journal of Organic Chemistry, 2018 Intramolecular oxidative amination of readily accessible aminocyclooct‐4‐enes provides rapid and regioselective access to the 9‐azabicyclo[4.2.1]nonane framework characteristic of the natural product anatoxin‐a (1). This has enabled the synthesis of sp3‐rich chemical scaffolds suitable for diversification.

European Journal of Organic Chemistry, Volume 29, Issue 5, 7 February 2026.The absorption spectra of amoxicillin degradation by colloidal MnO2 in the presence and absence of surfactants. Herein, the oxidative degradation of amoxicillin (AMX) by water‐soluble colloidal MnO2 is investigated spectrophotometrically at 298 K in both uncatalyzed and nonionic micellar‐catalyzed media (Triton X‐100 and Brij‐35).

J. Chem. Soc., Chem. Commun., 1989 2 pages, 1 table, 1 scheme. The amidyl radical intermediates, produced by photolysis of medium-sized lactams 7-heptanelactam (1), 8-octanelactam (3), and 9-nonanelactam (6) in the presence of (diacetoxyiodo)benzene (DIB) and iodine, undergo transannular hydrogen abstraction to afford intermolecularly functionalised compounds such as oxoindolizidines (4)

Chemical and Pharmaceutical Bulletin, 1991 Reductive amido bond cleavage reaction, previously elaborated by our laboratory for the synthesis of carbocyclic ribothymidine from readily available 2-azabicyclo[2.2.1]hept-5-en-3-one, was successfully applied to the synthesis of carbocyclic analogues of thymidine and related compounds.

Chemical and Pharmaceutical Bulletin, 1972 Monoester of benzylmalonic acid (I) and 3-carboxy-4-octahydroquinolizinone (V) were coupled with benzenediazonium salt to yield labile phenylhydrazones, Iia and VII, respectively. IIa was kept standing in chloroform or heated to give another phenylhydrazone (IIb). VIa was similarly converted into VIb.
