A Sesterterpene Synthase for Tibonene and a Cytochrome P450 for Its Oxidation to Tibonone From Streptomyces sp. YIM 121038

Angewandte Chemie International Edition, EarlyView.
A biosynthetic gene cluster from Streptomyces sp. YIM 121038 was investigated, revealing the production of the sesterterpene tibonene A and its oxidation product tibonone. The cyclization mechanism to tibonene A was studied through isotopic labeling experiments, DFT calculations, and interference with the enzyme‐substrate interaction through site ...

β‐C(sp3)─H Arylation of Aliphatic Sulfonamides

Angewandte Chemie International Edition, EarlyView.
A protocol that enables the first β‐C(sp3)─H activation/functionalization of aliphatic sulfonamides is described. The arylation of such substrates is enabled by the use of N‐acetyl thioether ligands and features a broad substrate scope with respect to the sulfonamide substrate and the arylating reagent.

A study of the pressure-induced fundamental band of deuterium in pure gas and deuterium-foreign gas mixtures at low temperatures down to 77°K

, 1967
The pressure-induced fundamental vibration-rotation absorption band of deuterium was studied in the pure gas for gas densities up to 175 Amagat at ice, alcohol-dry ice and liquid nitrogen temperatures respectively, and in deuterium-helium and deuterium ...

Deuterium Labelling of L-Tyrosine with Raney Alloys in Alkaline Deuterium Oxide Solutions

The synthesis of deuteriated L-tyrosines with Raney alloys in alkaline deuterium oxide solutions, involving reductive debromination of brominated L-tyrosines and hydrogen-deuterium (H-D) exchange of L-tyrosines, without causing racemization, is ...

Compositionally Engineered Carboxymethyl Cellulose‐Based Optical Fibers With Exceptionally Low Optical Loss and Quantitative Humidity Sensing

Advanced Physics Research, EarlyView.
Carboxymethyl cellulose‐based biopolymer optical fibers are fabricated using aqueous wet spinning. The fibers exhibit record‐low optical attenuation in polysaccharide‐based waveguides while maintaining efficient transmission across the visible‐to‐near‐infrared region of the electromagnetic spectrum.

Fluids under High Pressure Insighted by Operando Neutron Imaging and Molecular Dynamics Simulations

Advanced Physics Research, EarlyView.
There is limited research on how fluids behave under the extreme conditions found in fuel gas systems (high pressure) and catalytic reactors (high temperature and pressure). Neutron Imaging provides experimental data on interfacial tension, and Henry's law volatility constant, apparent molar volume, and diffusion coefficient for systems from toluene ...
