Deprotonative C(sp3)/C(sp2)–H (Multi)Silylation of (Hetero)Arenes Mediated by NaTMP

Angewandte Chemie, EarlyView.
An operationally simple protocol using a strongly basic sodium amide in combination with sterically emcumbered silicon electrophiles enables the deprotonative C–H (multi)silylation of a myriad of (hetero)arenes. Mechanistic investigations highlight the pivotal role of steric and coordination effects in controlling the regioselectivity and efficiency of

Discovery and Biosynthesis of the Novel Glycotetrapeptide Antibiotic Biffamycin A

Angewandte Chemie, EarlyView.
Genetic de‐regulation of a silent biosynthetic pathway allowed isolation and characterisation of a novel glycopeptide antibiotic named biffamycin A, which harbours unprecedented 5‐chloro‐4‐methoxy tryptophan and 3R‐hydroxy(α‐D‐mannoysl)‐D‐lysine moieties and is bioactive against MRSA and VRSA.

Concerted Proton and Electron Transfer in Heterogeneous Electrocatalytic CO2 Reduction

Angewandte Chemie, EarlyView.
Concerted proton‐electron transfer (CPET) enables CO2‐to‐CO conversion with significantly reduced energy cost compared to cation‐stabilized pathways. Under controlled mass transport of proton donors, CPET dominates at modest potentials. At higher overpotentials, a cation‐stabilized pathway is found to dominate.
