Chemistry – A European Journal, EarlyView.The total syntheses of (+)‐ and (−)‐myrioneurinol are described. This was achieved through two key steps based on a Prins‐type alkenylation of activated phenols to construct the central cycle of this natural substance, and a late‐stage “resolutive” Barton Mc‐Combie reaction which allowed the separation as well as the deoxygenation of both enantiomers ...

Distributive laws via admissibility [PDF]
arXiv, 2017 This paper concerns the problem of lifting a KZ doctrine P to the 2-category of pseudo T-algebras for some pseudomonad T. Here we show that this problem is equivalent to giving a pseudo-distributive law (meaning that the lifted pseudomonad is automatically KZ), and that such distributive laws may be simply described algebraically and are essentially ...

Carbohydrate Synthesis is Entering the Data‐Driven Digital Era
Chemistry – A European Journal, Accepted Article.Glycans are vital in biological processes, but their non‐templated, heterogeneous structures complicate structure‐function analyses. Glycosylation, the key reaction in synthetic glycochemistry, remains not entirely predictable due to its complex mechanism and the need for protecting groups that impact reaction outcomes.

Novel Microwave Plasma Source for Plasma Chemistry in Gases
Chemie Ingenieur Technik, EarlyView.A new microwave plasma source for plasma gas chemistry is introduced. Microwave energy is specifically coupled into defined gas volumes to activate chemically internal compounds such as N2, CO2 or H2O. The activation of N2 and the conversion of CO2 to CO are given as examples.
