Biphasic Model Describing Soybean Oil Epoxidation with H2O2 in Continuous Reactors

Epoxidized soybean oil (ESBO) is produced in industry by reacting soybean oil, at 60-70 degrees C, with hydrogen peroxide in the presence of formic or acetic acid. A small amount of sulphuric or phosphoric acid is necessary to catalyze the oxidation of the ...

Total Synthesis of Cyrneine A

Karl Gademann, Cindy Fellay

The tricyclic diterpene cyrneine A featuring a hexatrienal unit was prepared synthetically for the first time by a Heck reaction, a carbene ring expansion, and a reductive carbonylation. The structure of the natural product was assigned by X‐ray crystal an ...

The Role of Site-Specific Hydrogen Bonding Interactions in the Solvation Dynamics of N-Acetyltryptophanamide

Majed Chergui, Ahmed Maher Fahmy El-Zohry

Measurements of the ultrafast broadband UV fluorescence of N-acetyltryptophanamide (NATA) provide detailed information on its relaxation patterns in three different solvents: methanol (MeOH), water and acetonitrile (ACN). Several processes leading to excit ...

A solvent-responsive coordination cage

Rosario Scopelliti, Kay Severin, Benan Kilbas

The solvent-induced structural rearrangement of synthetic supramolecular structures typically requires a pronounced change in solvent polarity. We describe a ruthenium-based coordination cage, whose geometry and topology can be altered dramatically by usin ...

Labelling cell structures and tracking cell lineage in zebrafish using SNAP-tag

Kai Johnsson, Sambashiva Banala, Mako Kamiya

We present a method for the specific labelling of fusion proteins with synthetic fluorophores in Zebrafish. The method uses the SNAP-tag technology and O-6-benzylguanine derivatives of various synthetic fluorophores. We demonstrate how the method can be us ...
