Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application
European Journal of Organic Chemistry, Volume 29, Issue 19, 22 May 2026.Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...

Photo-Cycloaddition Reactions of 2-Pyrones [PDF]
Bulletin of the Chemical Society of Japan, 1990 Abstract Sensitized photoreactions of two 2-pyrones with five unsaturated compounds were investigated. The reactions of 2-pyrones with electron-deficient ethylenes gave [4+2]cycloadducts (3) and [2+2]cycloadducts (4) across the C5–C6 double bonds in the 2-pyrones.

Breaking Down Barriers: CorA Effectively Targets Staphylococcal Biofilms in Vitro and in Vivo
ChemMedChem, Volume 21, Issue 7, 14 April 2026.Corallopyronin A (CorA), a natural alpha‐pyrone antibiotic, penetrates Staphylococcus aureus biofilms and inhibits RNA polymerase. This work demonstrates CorA's superior efficacy compared to rifampicin and dalbavancin in reducing viable loads in biofilms both in vitro and in vivo. Graphic created in https://BioRender.com.
