Alkoxyallenes in Modern Synthesis: Reactivity, Catalysis, and Complexity Generation

Advanced Synthesis &Catalysis, Volume 368, Issue 17, 1 September 2026.
The last decade has witnessed a remarkable transformation in alkoxyallene chemistry. Although historically employed as synthetic equivalents of acrolein or as versatile 3C synthons, alkoxyallenes are now increasingly recognized as highly adaptable platforms for synthetic design.

A 3D Human Bone and Bone Marrow‐on‐a‐Chip Model for In Vitro Bone Remodeling and Immune Cell Maintenance

Advanced Science, Volume 13, Issue 51, 14 September 2026.
This study presents a human Bone (and Bone Marrow)‐on‐a‐Chip model based on native human bone scaffolds and autologous cells. Dynamic perfusion and sequential cell seeding replicate the physiological bone remodeling process in vitro, enabling the long‐term culture of functional, mature bone marrow immune subpopulations.

Chiral‐Induced Spin Selectivity Effect in a 1 nm Thin 1,1′‐Binaphthyl‐2,2′‐diyl Hydrogenphosphate Self‐Assembled Monolayer on Nickel Oxide

Advanced Science, Volume 13, Issue 52, 18 September 2026.
A self‐assembled monolayer (≈0.9 nm) of an axially chiral binaphthol phosphoric acid derivative on a ferromagnetic Ni/NiOx substrate shows chiral‐induced spin selectivity (CISS) magnetoresistance of 50%–80%. This thermally and chemically robust functional stack shows the way towards practical spintronic devices based on the CISS effect.

Excited‐State Antiaromaticity Relief‐Guided Discovery of 7‐Hydroxycoumarins as Photoacid Catalysts

ChemCatChem, Volume 18, Issue 17, 14 September 2026.
DFT and NICS studies are presented, in order to elucidate the relation of photoacidity with antiaromaticity relief of the excited state of 4‐substituted umbelliferone derivatives, leading to the experimentally optimum selection of photoacid catalysts for the acetalization reaction.
