A novel fusion tool to enable G protein‐coupled receptor structure determination

open access: yesActa Crystallographica Section D, Volume 82, Issue 6, Page 655-663, June 2026.
The development of a new fusion tool in which a β‐lactamase fusion tag and a binding partner enabled the structure determination of an antagonist‐bound G protein‐coupled receptor by cryo‐EM is reported.Structure determination of G protein‐coupled receptors (GPCRs) plays an important role in accelerating drug development against this medically important

Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application

open access: yesEuropean 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 ...

Total Synthesis of Novel Oxylipins: Plasmodiophorols A, C, and Epimers

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 19, 22 May 2026.
The first total syntheses of plasmodiophorols A and C, recently identified α‐linolenic acid‐derived oxylipins, were achieved from chiral cyclopentafuranone in 12–13 steps. The routes use enzymatic desymmetrization, epimerization, and diastereoselective Grignard addition, providing stereocontrolled access to the natural products and reliable standards ...
