Induced Photoelectron Circular Dichroism as a Probe for Distinguishing Diastereotopic Lone Electron Pairs

Angewandte Chemie, EarlyView.
Gas‐phase complexation of chiral methyloxirane by achiral phenol results in induced chiroptical response of phenol. Two pseudo enantiomer complexes are observed, corresponding to hydrogen bonding from phenol to either of the lone electron pair of the methyloxirane oxygen, denoted as Pro R and Pro S, with opposite chiral deformation of phenol and ...

Scalable High‐Force Zipping Electrostatic Actuators

Advanced Intelligent Systems, EarlyView.
An electrostatic actuator architecture is presented that combines high energy density with forces and strokes suited for wearable soft robotics. By folding patterned thin films into a scalable honeycomb of zipping units, performance becomes tunable through series–parallel design, achieving over 40 N and 28 J/kg.

Total Synthesis of the Spirocyclic Bis‐Indole Alkaloid (−)‐Owerreine via a [4+2] Annulation

Angewandte Chemie, EarlyView.
The total synthesis of the bis‐indole alkaloid (−)‐owerreine has been accomplished by a diastereoselective [4+2] annulation between an enamine and an α,β−unsaturated indolenine precursor to form the 3‐spirocyclic tetrahydropyridine linkage of the natural product. DFT calculations allow an understanding of the mechanism of the key annulation.

Comparing the Latent Features of Universal Machine‐Learning Interatomic Potentials

Advanced Intelligent Systems, EarlyView.
This study quantitatively assesses how universal machine‐learning interatomic potentials encode the chemical space into latent features, showing unique model‐specific representations with high cross‐model reconstruction errors. It explores how training datasets, protocols, and targets affect these encodings.

One‐Pot Amidation/C─H Halogenation by an Efficient Electrochemical Cascade

Angewandte Chemie, EarlyView.
A sustainable electrochemical cascade enables the one‐pot synthesis of regioselectively halogenated N‐aryl amides from readily available amines and acyl halides under mild conditions. The method merges amidation and C─H halogenation in a single operational step, delivering broad substrate scope, high selectivity, and scalability, and provides an ...
