Chemical Metabolomics: Chemical Biology Tools for Advanced Metabolism Investigations

open access: yesAngewandte Chemie, EarlyView.
The human metabolism has been investigated for several millennia. The metabolome is known for a high complexity due to a large number of different metabolites that are present at different concentrations. Metabolomics has been developed as a field to investigate the entire human metabolome and to elucidate disease development mechanisms.

Nickel‐Catalyzed Enantioconvergent Arylation of Unactivated Cyclic Electrophiles: Asymmetric Synthesis of 3‐Substituted Pyrrolidines

open access: yesAngewandte Chemie, EarlyView.
Metal‐catalyzed enantioconvergent substitutions of unactivated cyclic electrophiles by organometallic nucleophiles have not previously been reported. Herein, a chiral nickel catalyst is described that achieves this objective, coupling 3‐iodopyrrolidine derivatives with arylzinc nucleophiles.

Diazo Transfer From Nitrous Oxide Employing Phosphorus Ylides

open access: yesAngewandte Chemie, EarlyView.
A phosphorus ylide‐mediated strategy achieves the direct fixation of nitrous oxide (N2O) to access diazo compounds, which after intra‐ or intermolecular trapping, afford N2‐containing organic building blocks. This approach provides an alternative to hazardous diazo‐transfer reagents and establishes N2O fixation as a sustainable methodology.
