Asymmetric Organocatalytic Synthesis of Sulfone‐Containing (Dihydro)pyrans via Formal (4+2)‐Cycloadditions of Allenylsulfones or Propargylsulfones and Michael Acceptors

ChemCatChem, Accepted Article.
The activation of electron poor allenes with Lewis base catalysts allows for unique transformations and chiral isochalcogenoureas were recently introduced as powerful catalysts for allenoate‐based (4+2)‐cycloadditions. We herein now report the use of these catalysts for the activation and control of allenylsulfones and propargylsulfones for asymmetric (

Development and Validation of a Laboratory‐Scale Methanol Synthesis Mini‐Plant and Digital Twin Simulation

Chemie Ingenieur Technik, EarlyView.
A methanol mini‐plant and its digital twin were developed to study flexible feedstocks, reactant recycling, and product condensation. Experimental results show good agreement with simulations, allowing systematic investigation of process parameters. Tests with biomass‐derived syngas demonstrated the feasibility of industrial COx sources.

Development of Carborane‐Based Halogenated Naphthyridinone‐Analogues as Cannabinoid Receptor Type 2 (CB2R) Ligands

ChemMedChem, EarlyView.
There is no suitable radioligand for positron emission tomography imaging of CB2R overexpression for routine clinical usage. Herein, the synthesis, characterization, binding affinity, and docking studies of carborane‐based halo‐substituted naphthyridinone derivatives as CB2R ligands are presented.

Photocatalytic Oxygen Evolution with Prussian Blue Coated ZnO Origami Core‐Shell Nanostructures

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Prussian Blue and its derivative hold significant potential for photocatalytic oxygen evolution. IN this contribution the photocatalytic oxygen evolution reaction (OER) was characterized using a hybrid catalyst consisting of Prussian Blue coated ZnO nanostructures. The resulting heterojunction, which was characterized both structurally and functionally,
