Gold‐Catalyzed Synthesis of Fluorenones via Intramolecular C–H Arylation

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Starting from 2‐diazobenzophenones, a straightforward synthesis of valuable fluorenones via a gold‐catalyzed one‐pot oxidation, C–H activation, and cyclization is described. The addition of ascorbic acid, the correct selection of the counteranion of the 2‐diazobenzophenones, and the use of terpyridine as an auxiliary ligand are crucial for the reaction

Iterative Use of Regiocomplementary Flavin‐Dependent Halogenases Gives Access to Unique Halogenation Patterns

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
The halide motif is ubiquitous in organic synthesis, facilitating fine‐tuning of molecular properties and functionalization using substitution and cross‐coupling reactions. Combination of different flavin‐dependent tryptophan halogenases enables the installation of novel halogenation patterns on l‐tryptophan, which can be orthogonally addressed in ...

Electrochemical Chemo‐ and Regioselective Heterofunctionalization of Tropones via C(sp2)H Derivatization

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Simple and selective. The electrochemical heterofunctionalization of activated tropones is achieved using readily available inorganic salts. A theoretical model, based on cyclic voltammetry and quantum chemistry calculations, predicts both reactivity trends and site selectivity.

Assement of iodine content in most of the branded common salt [PDF]

open access: yes, 2007
Sodium chloride, also known as common salt, table salt, or halite, is a chemical compound with the formula NaCl. Sodium chloride is the salt most responsible for the salinity of the ocean and of the extra cellular fluid of many multicellular organisms ...

Sugar Functionalized Collagen Material for Local Modulation of Innate Immunity

open access: yesAdvanced Science, EarlyView.
Modulation of the innate immune response at the implant site can significantly influence adaptive immunity. A mannose‐functionalized collagen patch, termed the Local Immunotuning Patch (LIP), has been designed to engage mannose receptors on antigen‐presenting cells while exhibiting antibacterial properties. LIP orchestrates complex immune pathways that
