Synthesis of Sulfated Sn–Zr Mesoporous Catalysts for the Selective Dehydration of Hexose‐Type Monosaccharides

open access: yesChemistryOpen, EarlyView.
The synthesized SO4/Sn–Zr–SBA‐15 shows high activity in fructose‐to‐5‐hydroxymethylfurfural (HMF) dehydration. Acid sites with positive synergy effect between metals and SO4= improve catalytic behavior Synthesis of combined Brønsted and Lewis acid sites in SBA‐15 by Zr and Sn incorporation onto the mesoporous support, followed by a sulfation procedure ...

Studies Concerned with the Structure and Synthesis of the Anti‐viral Tropolone Glycoside Liriosmaside A

open access: yesChemistryOpen, EarlyView.
The core of the anti‐viral troponoid natural product liriosmaside A lacking the 3‐hydroxy‐3‐methylglutaric acid (HMGA) side‐chain at C6′ has been prepared. The early steps involved the gem‐dibromocyclopropane‐mediated ring‐expansion of a readily‐obtained Robinson annulation product.

Advances in Molecularly Imprinted Polymers for Bone Biomarker Detection and Therapeutic Applications

open access: yesChemistryOpen, EarlyView.
This review highlights the emerging applications of molecularly imprinted polymers (MIPs) in bone regeneration and diagnosis. MIPs facilitate osteogenic treatments by guiding stem cell differentiation and delivering bioactive molecules and enable precise detection of bone turnover biomarkers via MIP‐based sensors, offering promising strategies for next‐
