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‐

One‐Step Aqueous Synthesis of Glycosyl Pyridinium Salts, Electrochemical Study, and Assessment of Utility as Precursors of Glycosyl Radicals Using Photoredox Catalysis

open access: yesChemistryOpen, EarlyView.
Unprotected glycosyl pyridinium salts may be accessed in a single step from the corresponding unprotected sugar in aqueous solution. Whilst meta‐ and para‐substitution is well tolerated, ortho substitution of the N‐heterocycle inhibits product formation. Electrochemical studies revealed reduction potentials in the range of −0.9 to −1.4 V.
