Optimization of Steroid Photochemistry and Its Application in the Synthesis of 5,6‐Dihydro‐Ophiopogonol A

Chemistry – A European Journal, EarlyView.
Steroid photoreactivity was a major topic in the last century. This study revisits it by exploring the photochemistry of Δ1‐keto‐steroids, offering an efficient method to modify the classic steroid 6/6/6/5 ring system. This approach enables the transformation of accessible steroids into rare ones, demonstrated by synthesizing 5,6‐dihydro‐ophiopogonol A

Molecular Fragmentation as a Strategy to Access Hyperpolarised Compounds from Para‐Hydrogen

ChemPhysChem, Accepted Article.
Hyperpolarisation significantly increases the detectability of molecules in magnetic resonance spectroscopy and imaging. Beyond recent advancements in hardware and catalyst design, this article discusses harnessing the inherent chemical reactivity of hyperpolarisation target molecules as a strategy to expand the scope and versatility of para‐hydrogen ...

Open‐Chain Tetrapyrroles Meet Metal Ions in the Functional Molecular Material Science

ChemPlusChem, EarlyView.
Open‐chain tetrapyrroles, synthesized via oxidative cleavage and condensation, offer greater structural flexibility than cyclic counterparts like porphyrins. Their tunable electronic and geometric properties through metalation enable applications in bioimaging, therapies, ion sensing, chiroptical materials, and spintronic devices, making them valuable ...
