Who Activates the Nucleophile in Ribozyme Catalysis? An Answer from the Splicing Mechanism of Group II Introns

Ursula Röthlisberger, Giulia Palermo, Lorenzo Casalino

Group II introns are Mg2+-dependent ribozymes that are considered to be the evolutionary ancestors of the eukaryotic spliceosome, thus representing an ideal model system to understand the mechanism of conversion of premature messenger RNA (mRNA) into matur ...

Enantioselective Access to Spirocyclic Sultams by Chiral Cp-x-Rhodium(III)-Catalyzed Annulations

Nicolai Cramer, Van Manh Pham

Chiral spirocyclic sultams are a valuable compound class in organic and medicinal chemistry. A rapid entry to this structural motif involves a [3+2] annulation of an N-sulfonyl ketimine and an alkyne. Although the directing-group properties of the imino gr ...

Control of Reaction Systems via Rate Estimation and Feedback Linearization

Dominique Bonvin, Julien Léo Billeter, Diogo Filipe Mateus Rodrigues

Abstract of the conference paper The kinetic identification of chemical reaction systems often represents a time-consuming and complex task. This contribution presents an approach that uses rate estimation and feedback linearization to implement ...

TADDOL-based phosphorus(III)-ligands in enantioselective Pd(0)-catalysed C-H functionalisations

Nicolai Cramer, Julia Pedroni

Monodentate TADDOL-derived phosphoramidites and phosphonites are versatile chiral ligands for enantio-selective Pd(0)-catalysed C-H functionalisations. They enable highly selective cyclisations to access a wide range of chiral carbo-and heterocycles. The h ...

Effect of ammonia on the decomposition of ammonium formate over Au/TiO2 under oxidizing conditions relevant to SCR: Enhancement of formic acid decomposition rate and CO2 production

Oliver Kröcher

Ammonium formate (AmFo) and formic acid decomposition were carried out in the presence of excess O-2 and H2O over 0.5 wt%Au/TiO2 anatase monolithic catalysts using various contact times and temperatures between 160 degrees C and 300 degrees C, under spray ...

Elsevier Science Bv2014

The reactions of dolomite with portlandite have been studied at well-spaced temperatures between 20 degrees C and 85 degrees C using XRD Rietveld, TG and SEM methods. The results show quantitatively the faster rates of reaction at higher temperature. Isoth ...

Chiral Phosphoric Acid-Catalyzed Enantioselective Three- Component Aza-Diels-Alder Reactions of Aminopyrroles and Aminopyrazoles

Jieping Zhu, Thibaut Christian Courant

A highly stereoselective three-component Povarov reaction, catalyzed by (R)- and (S)-BINOL hydrogen phosphate, was achieved for the first time with aminopyrroles and aminopyrazoles as 2-azadiene precursors. A variety of aldehydes, enecarbamates, amino-subs ...
