Stereoselective synthesis of β-sulfinylamino isocyanides and 2-imidazolines
An efficient asymmetric synthesis of -sulfinylamino isocyanides is reported on the basis of the highly diastereoselective addition of 9-isocyanofluorene to optically pure N-tert-butanesulfinimines.

Isocyanide-based multicomponent reactions towards cyclic constrained peptidomimetics
In the recent past, the design and synthesis of peptide mimics (peptidomimetics) has received much attention. This because they have shown in many cases enhanced pharmacological properties over their natural peptide analogues.

Superlattice Architectures for Advancing Photothermal Catalysis: Mechanisms and Applications
This paper provides a timely overview of superlattice architectures in photothermal catalysis, with a systematic review on mechanisms at both atomic and macroscopic scales in different processes, challenges, and future opportunities. ABSTRACT Photothermal catalysis has emerged as a powerful strategy to complement photocatalysis by harnessing full ...

Isocyanides inhibit [Fe]-hydrogenase with very high affinity
[Fe]-Hydrogenase catalyzes the reversible activation of H2. CO and CN− inhibit this enzyme with low affinity (Ki≅0.1mM) by binding to the iron site of the bound iron-guanyrylpyridinol cofactor.

Smiles/Pudovik/Phospha–Brook Cascades from Passerini–Smiles Adducts
The Passerini–Smiles reaction of aliphatic ketophosphonates affords starting materials for complex cascades triggered by a first Smiles rearrangement. The cascade showcases the power of phosphorous based transformations. Here the reversibility of the Pudovik reaction allows a further Truce–Smiles reaction enol before final Pudovik/Phosph–Brook sequence.

Chemoselective addition of isocyanides to N-tert-butanesulfinimines
The reaction of isocyanides with N-tert-butanesulfinimines shows remarkable chemoselectivity. β-Sulfinylamino isocyanides are formed exclusively with aromatic sulfinimines, while α-sulfeneimino acetamides result when using aliphatic derivatives.

Metal-Mediated Addition of N-Nucleophiles to Isocyanides: Mechanistic Aspects
Despite the long history of the investigation of nucleophilic addition to metal-bound isocyanides, some important aspects of the reaction mechanism remain unclear even for the simplest systems.

Fungal‐Bacterial Interactions in Polymicrobial Infections: Hidden Threats
ABSTRACT Polymicrobial infections involving fungi and bacteria represent a major and increasingly recognized clinical challenge, in which interkingdom interactions significantly amplify disease severity, antimicrobial resistance, and treatment failure. Rather than passive co‐existence, fungal–bacterial communities form highly coordinated systems driven
